Gee is a very friendly and hospitable person. She tried to make my stay as comfortable as possible. I have lived in a cosy room with a balcony. The room had a comfortable bed and small desk. The view from the balcony was nice. The kitchen and bathroom were large and the flat has also a high ceiling.
The tram station was just in front of the door. U-Bahn Osloer Str. is 5min walking distance, which makes it very easy to travel around the city, as I could take either U8 or U9 direction. Living with Gee was great, she's very kind, she also quickly solves any problems and shows great hospitality. I would definetely recommend this place and would come again, if I need a stay in Berlin :)
