Kristina's place is cozy, stylish and clean. It looked at the pics a bit cramped but in fact, is comfortable and the bathroom is big. There is a tram stop close to the apartment so it was easy to reach the city centre, with tram 12 you are within 20-25 minutes at the Friedrichstrasse or with the connection to U-Bahn / S-Bahn at the Alexanderplatz.
