In brief: Hotel location between Hamburg-Altona station and Reeperbahn, personnel friendly and helpful, room OK. - In detail: I booked this hotel mainly because I was going to take a train from Hamburg-Altona station early next morning. I stayed only one night and left so early that I couldn't assess the breakfast. - Hotel room and bathroom were OK. - One minor complaint was that I had problems logging to the wifi with the first username I was given, but with the next username everything worked fine. - Afterwards I had to write to the hotel's reception in a lost property case. The reception quickly sent an informative reply message where they told that the property had not been found. That was excellent customer service! By the way, the lost property was later found from another place, so Zleep Hotel had nothing to do with the case. - For those who arrive by train: Check if your long-distance train continues to Hamburg-Altona station, which is closer than Hamburg Hbf. On the other hand, you can take from the Hbf a local S-bahn if you know how to use it. S-bahn station is just by the hotel at the end of Reeperbahn. Learned it later...
