We stayed in Marie's appartment for 8 days and it was really good experience. The communication and key handover worked perfectly and she made lots of efforts to make sure that everything works. The appartment is very nice, clean, quiet and comfortable and it has all utilities that one might need for holiday stay. The location is absolutely perfect and only 10 minutes by U-bahn to the center of Berlin. There are plenty of shops and cozy restaurants in the close neighborhood. All in all we enjoyed the whole stay and would definately recommend it to our friends.
