We loved staying in Faina's flat. It had plenty of space for a family of 4 adults and was really comfortable. The flexibility on arrival and departure times was perfect for us and we were met at the flat and given really useful information about the flat and the area. The location is great with a lovely park across the road and easy access to S-Bahn and U-Bahn. There are nice restaurants and cafes nearby, but you are also very quickly into any part of Berlin you care to choose. We would recommend Faina's flat. Her organisation was perfect and the flat was just what we wanted.
