We used the Apartment for a short trip of 4 days in Prague and I can only recommend you this as starting point of your trip. Communication in advance was helpful and quick (they answered within a few minutes). The Check in at their Office was uncomplicated and professional, even though we were an hour early ;) Because the parking situation is a little tricky (as it seems to be everywhere in Prague) they recommended us some parking space nearby, which we used. Tram and Metro stations can be accessed easily by a few minutes of walking. It’s about 20 min walking distance from the historic old town.
The Apartment was clean (top!), bed sheets, towels and some coffee powder, tea, sugar, salt and even ice cubes were supplied! :) The Apartment has a nice table football and a Sauna that can fit 2 people. From one room you can also reach a back yard.
Not only is the apartment fully stuffed with different kitchen tools, a dishwasher, a washing machine and some cleaning items. It is also beatifully furnished, as the pictures show :)
