Luggage storage

Dogs are always welcome at all a&o locations! You can bring a maximum of 2 dogs in your room for a fee of 10€ per night and dog.
Unfortunately it is not possible to bring dogs into the multi-bed rooms, as it is possible that it would make other guests uncomfortable. For the same reason we ask you not to bring dogs to the breakfast room. We appreciate your understanding.

Room categories

In almost all of our a&o establishments, you can find single, double and family rooms, however you can also book a bed in a dorm for four to eight people.

*Exceptions to this rule are the a&o Hostels Köln Dom / München Hauptbahnhof / Hamburg Hammer Kirche, as these hostels only have private rooms, and are therefore unable to offer bookings for a bed in a dorm.*

Therefore, you have two options for booking with a&o:

• The First option means…
You are booking a private room i.e. a single, double, or family room. The price includes bed linen, hand towels, 2-in-1 shampoo, a hairdryer, and you can enjoy the convenience of your own bathroom.

• The Second option means…
You are booking a bed in a dorm room. This option offers you affordable accommodation in an uncomplicated atmosphere. With this option, each room has its own bathroom with 2-in-1 shampoo and a hairdryer. You can also add bed linen and hand towels to your booking.

*The only exception is our a&o Hamburg Reeperbahn, where there are still a few bathrooms on the floors.*

Rules of the house

You can view and download the house rules here.


You can of course also bring your own food when staying with us. Our tip: It is best to check in advance whether the a&o you have booked offers a guest kitchen where you can prepare your meals.

You can find out either by reading the e-mail sent to you 48 hours prior to your arrival or by checking our website here.

Ticket bookings

If you are already on-site, please ask at the reception for selected tickets. Our friendly staff will be happy to help you.

Of course, you can already book selected tickets on our website upon your arrival. Simply choose an a&o city and get some inspiration. For example we offer WelcomeCards which already include a ticket valid for public transportation and huge benefits for several leisure and culutural activities.


Every a&o offers free Wi-Fi in all public areas, such as the lobby or the bars, and in every room as well.


Wheelchair-accessible rooms are available in almost all a&o HOTELS and HOSTELS. Feel free to call us at +49 30 80947 5110 to get more information.

Guest kitchens

We offer community kitchens with full kitchen equipment in some cities for city dwellers, for example for solo travellers, for couples, families and friends as well as for smaller groups. More information is available here.

Kids’ Corner & child care

Families find a Kids’ Corner in every a&o with toys, a painting board, coloring pencils and children's books. In some a&o's, the small children's playgrounds even have slides or playhouses. Your children can have a good time while you enjoy a cup of coffee in the lobby or in the breakfast room.

Find more information about our family benefits here.

We’re sorry to say that we do not offer hotel child care services. However, we can provide you with a good babysitter network for some cities that you can contact independently.

Room cleaning

At a&o we carry out daily room checks which consist of:
i) refilling hygience products and emptying bins
ii) no daily cleaning with chemicals in respect to our natural resources
iii) basic cleaning after check out.

We are always striving to help the environment that's why we don't change the towels daily. Please hang them on the towel rail and do not leave them on the floor. Fresh towels can be purchased at the reception for a small fee.


Since January 1, 2008 all of our locations are smoke-free.

Towels / Bed linen

All single, double and family rooms come with bed linen and towels. Only guests in multi-bed rooms need bed linen and towels, if they didn't bring their own. You get bed linen for 3.50€ and a towel for 1.50€ either at the reception or as an online feature when booking your stay.
In family rooms (grand)parents sleep a double bed (bed linen included) and their (grand)kids in one or two bunk beds. Families put fresh linen on their children's bunk beds themselves.

Women's rooms

Of course, we offer dorm rooms just for women. You can simply book them online – a pink banner shows the correct room category.

Automobile Association discount (e.g. AA UK)

All ARC Europe members (such as AA UK or AAA USA) get 12% off the daily-updated overnight rate at all a&o HOTELS und HOSTELS and a free, non-alcoholic soft drink (kids under the age of 12 get a free ice-cream).

Young drivers with an ADAC membership ('Junges Portal') get 12% off and free Wi-Fi instead.

All information with this reduced booking rate here.

Booking cancellation

It depends on the rate you booked. If you booked using our Flex-Rate, then you can cancel at any time. Otherwise the room will be kept available for you until 6 pm on the day of your arrival. Please let us know if you will arrive later. The Fix-Rate is, as the name says, "fixed" and cannot be cancelled. The price cannot be reimbursed even if you do not stay here. That's why this rate is especially low. For groups of 10 or more there are special cancellation rules that you can find in our Terms and Conditions.

Children's discount

Children under 7 years of age stay free of charge in their parents' room. The room price is based on the number of travelling parents (guardians). Little ones are always welcome! We can provide you with free children's beds (recommend up to the age of 2 years) and high chairs, when available.

Facebook discount

Social media are great communication networks that we really like! This way we can interact with our (potential) guests. That's why fans of our Facebook page also get 5% off the daily-updated price.
If you go to our Facebook page now and become a fan, you can then enter the following code when booking online: imafan

Frequent guests

As a frequent a&o guest you get - similar to bigger airlines - a special treatment. For 69€ you can order your personal Traveller Card at each reception desk or via telephone / E-Mail. The card will be send by post (on-site you will get a temporary card). You find all advantages for you as our guest here.

Group deposit

We don't request a deposit, but we request that groups behave themselves properly.

Long-term guests

If you stay at one of our a&o HOTELS and HOSTELS for a longer period of time, we recommend purchasing a Traveller Card. It offers exclusive prices for frequenters and other great advantages. Find more information here.

When travelling with lots of people or at regular intervals, we're happy to advise individually. Our competent sales team deals with your requests at: [email protected].

Payment options

You can choose from a range of payment options. You can pay by instant bank transfer, credit card (VISA or MasterCard), PayPal, Amazon Payments or direct debit. Paypal payments are charged with a 2.45 € processing fee when your amount is lower than 200 €. You should only use the direct debit option if your arrival is not in the next 5 days.

Press discount

Journalists get a 20% discount on overnight stays. MICE Travel Card holders also get to use this special price. Please contact [email protected] to make a reservation and show your valid press pass at the check-in counter.

Pricing at a&o

Our prices are determined by availability – completely fair, completely transparent! That means that if beds of one room category are in short supply at a specific date, then the prices go up. And if the desired occupancy rate has not been reached, then the prices also fall automatically. What does that mean for you? Basically, the earlier you book, the lower the price. Those who make decisions on the spur of the moment also benefit from exclusive last-minute deals – of course, only as long as the respective category is not fully booked.

Rail pass discount

Guests with a valid InterRail, Eurail or GermanRail pass receive a 10% discount on the daily rate of accommodation in all a&o's. Find all information including our online discount link here

Student discount

Each student with a valid ISIC- oder ITIC-ID card gets 10% off the daily-updated rate at all a&o HOTELS und HOSTELS including a free, non-alcoholic soft drink. Simply type in the discount code "isic" into the appropiate field when booking online.

Surcharge for single occupancy

We don't have a surcharge for single occupancy. You can find our current prices on each location's website.
