We stayed in Mia's apartment for 4 nights and were very comfortable the whole time! The unit is very clean and spacious and just as described. The extra half bathroom was very convenient and we were even able to do a load of laundry during our stay. The only one problem we encountered was poor water pressure in the shower, but otherwise everything was very comfortable. The apartment is a very short walk to the Friedrichstrasse station which is well connected with the airport and the rest of the city. Mia was very responsive to all our questions and I would highly recommend her place!
