This is an apparment I would definitely recommend.
The host if very professional and the check in went smoothly (there is a receptionist at the building). Parking in the backyard or downstair garage (car elevator) is possible for 20 euros a night, which is great.
The host gives out written details about the area with tips on where to eat, supermarkets, places to visit and so forth.
The appartment has a high standard and I am very happy with our stay (air condition in the bedroom).
We brought our baby daughet and they had brepeared a baby bed and there where no noise at night.
For our next trip to Prague we will most likely book this appartment again
