The apartment was exactly as advertised and was very enjoyable. The location is outstanding. Very easy to reach (3 minute walk) to the M2 Tram to/from Alexanderplatz or the S-Bahn (Prenzlauer Allee station) from anyplace. It is in a fantastic neighborhood with a lot of dining and bar options within a 10 minute walk. The grocery store is down the block. The apartment is quiet and well set up. The S-Bahn station is nearly behind the apartment, and trains come and go day and night, but are something you don't notice at all unless you have the windows open and are in the bathroom or kitchen.
The apartment is roomy and well furnished. We found it to be very comfortable.
We highly recommend this apartment and would stay in it again if ever in Berlin.
