Frank was a Great Host !!Communication was really easy and he was always there to help us whatever question or doubt we had.
The apartment is exactly how it looks in the pictures. Really clean and tidy and it has everything you need to make a good stay! Location is just great! Really close to helmholzplatz where a lot of restaurant variation can be find .. and he neighborhood is delightful.
I would totally recommend franks apartment for a great stay in berlin !
