I stayed in Gili's Airbnb for 4 nights with my friend and sister. We had a really great stay there and there was definitely enough room for all 3 of us. Gili was really welcoming and friendly despite us arriving late. It was also very easy to get in contact with him throughout the long weekend. The Airbnb was also very clean and warm, the wifi was great as well.
Location wise the Airbnb was very convenient; it is just around the corner from a U-bahn meaning we could go to many of the main touristy spots (i.e Brandenburg Gate & Alexanderplatz) very easily. The neighbourhood itself also has many restaurants to choose from; there's a very good Italian restaurant at the bottom of the street and a burger place called International Burger nearby.
