We spent a wonderful weekend in Mechtild's house. The apartment was very clean, tidy and warm. The apartment had all the necessities for a short stay.
We appreciated the good connection to the center, only three stops of metro to the Old Town. The tram stop is in front of the door and the metro station is next to the corner! Mechtild was very kind giving us maps and various information about Prague. She was available at any time for any information during our stay.
The only down side was the lack of good internet connection. Other than that I would definitively recommend!
