The flat is comfortable and clean. Parwana has very clear and well described rules. It's close to an U-Bahn station, so it makes it easy to move everywhere. It's also close to supermarkets and a nice park with a lake.
From my point of view, it works more like a hostel than an Airbnb concept, because one must share common areas with other guests. So one pays not for an apartment but for a room.
