Frank's flat was perfect, the location is brilliant, close to everything you might need (supermarkets, drugstore, restaurants, etc.) during you stay. The area is nice, close to the main touristic attractions. The pictures are a perfect reflection of the flat. The bed is okay and the flat is very warm ( very good isolation). Frank was a great host we saw him on thine first day and he pointed us some nice places to visit and explain a little bit of how the things works In Berlin ( subway, tram, etc).On the donwside however the cleanliness of the flat could be improved, specially on the toilet, but nothing too serious. Overall was a great experience and we definitely recommend the Frank's flat.
