The hotel is 2-3 stars. It was very clean, the room was a good size. BUT: the room I was given overlooked the tramstop outside on Thomas-Mann Strasse. There was no airconditioning, and with temperatures outside of c. 33C, I had a choice of a small amount of fresh air through the top of the window plus incessant tram noise from stopping and starting, or no fresh air and relative silence. It was very difficult to sleep during the first part of the night as a result. When I mentioned this to reception I was told that no airconditioning was a hotel policy, as it would double the electricity costs and reduce sustainability. My .argument that the extra electricity ciould be sourced renewably from wind or PV was ignored. Goopd breakfast (extra cost 12 Eur). .
