I can highly recommend this place from Gianni. Gianni and his daughter are the mosts friendly hosts here in Berlin I think. The apartment is big, sunny and has a balcony. The blue bedroom is an experience on itself and is really cosy. Also the living room is cosy. So this is all what you need when you are going for a trip to Berlin. On top of that, the location is also perfect ( close to tempelhoferfeld and close to the metro). So, I am definitely coming back when I am again here in Berlin.
