First of all the location is great, there is a U station 1 minute from the hotel, plus many buses are close by. A main train station is about 6-8 minutes walk and it was so easy getting anywhere in Berlin with public transportation.
There are many restaurants in the area and lots of shopping options including a supermarket open until late , around 11:00 p m .
The staff all were friendly and helpful.
I do have 2 minor issues, one is there wasn't a door to the bathroom, I was staying alone so it didn't bother me but if you are staying with another person and this can be issue try to check about other rooms, maybe they do have a door. There was a door to the toilet area.
The second thing was the curtains in my room, there was a small gap in between them so light got to the room while I was sleeping. I'm a light sleeper with ot without light so I don't know if I can blame the curtains for my early wake up time in the morning. They did try to fix it and after the first night it wasn't as bad.
