Very nice and fantastic apartment.
The common areas are plenty of space and the decoration is really stylish as shown in the pictures and amazingly luminous. It also has a useful terrace, that although face to the interior patio of the block, being the last floor it is really sunny and nice.
It accommodates comfortably 4 people (5th should sleep in the common leaving room).
The apartment has all required facilities, and we didn´t miss anything during our staying.
The apartment is well communicated by public transport (tram, train, bus) and in a nice neighborhood, it takes around 45 minutes walking for a nice avenue to Alexanderplatz, and around 20 minutes by tram.
There are also many shops and big supermarkets close to it, open until late night. Also close to many restaurants (I did not try them as they did not look very attractive to me).
Birgit is also very helpful, receives you in person explaining you anything you require to know about her house, and she replies your messages promptly.
The apartment is really good value for money, and I recommend it without any hesitation.
