The house is comfortable. The room is big enough. Actually is a living room with a sofa (becaming a bed), some shelves, a tv. Not a real desktop but a little bar counter. Equipped Kitchen to prepare fast meals. Nice and clean bathroom.
One problem was the WI-FI, barely functioning on smart-phone, discontinous or inexistent on laptop.
The area is very quiet, no noises at all. No U-Bahn nearby but very well-connected to Alexander Platz and Mitte (and its transports) by tram, walking distance. A lot of market where buy goods and food.
Ronny was nice, very kind, polite and correct.
At the end of the day a good place where spend some days in Berlin.
