The room is as adverted and even more. What the advert and reviews don't tell you is how amazing the hosts are. Monica's apartment is centrally located, just a mere 3 minute walk from Alexanderplatz station. From the apartment, it is a short walk to the Berliner Dom, and the Museum Island. There is a bus stop in front of the apartment. I took Bus 100 to go to the Victory Column, Reichstag Building, Brandenburg Tor, etc. And if you need to go to the opposite direction, the tram station is a few minutes walk (it is near Alexanderplatz).
The room is clean, streamlined and tastefully decorated. You can tell it was done by an art person. Monica works for a film company and Yvonne is an architect. I stayed a total of 3 nights, and I slept very well. The bed and pillows were comfortable. You have your own private entrance and your own bathroom. I felt as if I am home because of these 2 things.
This is a 5-star rated accommodation as far as I am concerned and the hosts are more than awesome.
