Quality and safety

The quality of our product and the associated safety of our guests is very important to us. We also want you and your kids to feel in good hands!

"We seek transparency and want to let you know how we work!"

For this reason, we aim to get tested and certified by external certification bodies on a regular basis in order to guarantee our guests an above the average standard in the industry. 
The quality of A&O hostels has been reviewed and certified by the following institutions:

2** classification by Dehoga for A&O HotelsDEHOGA

All our houses have been awarded with two stars by the DEHOGA, the German Hotel & Catering Association responsible for the hotel star rating; excluding A&O Köln Dom and A&O Hamburg Reeperbahn. Some of our properties also received the extra ‘Superior’ for above-average performance in this category.


Annually tested and proved by TÜVSince 2007 A&O is tested by TÜV Rheinland annually with regard to our ‘Youth Hostel Quality Standard’. In this procedure the institution determines whether our offer ‘Youth Hotel’ has been implemented appropriately for young people. This is seen from the perspective of a customer, checking if certain standards were met, such as the cleanliness of the rooms, the hygiene in A&O’s bathrooms, the breakfast or the competence and friendliness of staff.
Furthermore, the optimal organisation and consistent quality of the internal processes is evaluated as well as the compliance of youth protection regulations.

We have met all the criteria to the satisfaction of TÜV and, as a result, have been vertified with the quality label ‘Youth Hostel Quality Standard’.

Awarded label of the Association of Youth Travel Reisenetz

‘Reisenetz‘ is the Association of Youth Travel which awarded A&O with its quality label ‘checked quality’, interestingly being the first and single accommodation chain to have ever received this label.

Bundesforum Kinder- und Jugendreisen e.V.

award for good quality management in the Youth travel segment
The Federal Forum for Children and Youth Travel runs its own test system called QMJ (quality management for youth travel). This quality label informs about defined standards and awards its stars accordingly, similar to the DEHOGA association. Most German A&O hostels have been certified with 4 out of 5 possible stars (the exception being Berlin Zoo with 3 stars).

CO2 footprint


Co2-Zertifizierung von Viabono

Last year A&O has instructed an independent institution called Viabono to check all our buildings on their CO2 emissions. This CO2 emission check allows a measurement of the climate impact on human activities. The average level of CO2 emissions of all A&O hostels is 8.96kg CO2/ overnight stay. This value in fact corresponds to the climate efficiency class B in the categories youth accommodations, being 3 times lower than in other two and three star hotels. The average value is 26 kg CO2/ overnight stay. We can achieve this climate friendly value by means of our simple and functional facilities plus our optimal use of space.

We are pleased to claim that we have been the first German hostel chain to have ever carried out such an emission check so far.

Here you find some examples of our certifications:

A&O Berlin Friedrichshain A&O Hamburg Reeperbahn A&O Wien Stadthalle

Because we really care about the environment and want to educate our guests, we have developed a CO2 calculator in cooperation with Viabono making it possible to plan eco-friendly school trips. To do the CO2 check, simply click here.
