The hostel is in the middle of the official red-light district of Hamburg and I had a hard time locating the entrance, because it is in a tiny lane sandwiched between a shop selling BDSM items and a dance bar. The photos I have of the area (you bet I took photos) are not family-friendly and best left out.
Also, it is worth keeping in mind that this hostel does not have lifts. It is essentially three separate buildings connected by passages and working as one hostel. There are rooms on the ground floor, which may be more accessible for people with disabilities.
I had to change my room three times, as in the first room, the bathroom/toilet doors wouldn't close!!!. In the second room, the bathroom/toilet doors wouldn't lock.
However, the staff were very polite and did their best to assist.
The buildings are old and they were the first A&O hostels which had a combined bathroom/toilet and bath tubs!!!
There is a Penny supermarket just down the corridor and Hamburg harbour is a few minutes away on the other side of the road. The S-Bahn station is a few (50-100) meters away from the hostel and there are trains running directly to and from Hamburg Airport.
This is a hostel I would definitely recommend if you want to look at Hamburg's night-life district.
