Nice place for a short stay (4-5 days) but not more. The tram station is just in front of the house, which is convenient. With many bars, supermarkets and nice restaurants close to it.
Concerning the flat, some inconveniences : the bathroom is humid with some walls damaged, the room got 2 separates sheets too. No microwaves in the kitchen. The wifi does not work at all. There is many noise too outside because of the crossroad with sirens, cars, tramway noises and bus.
To finish the flat is really well located. (Close to Alexanderplatz and Mauerspark)
