We were a family of 4 and stayed in a nice, clean, equipped apartment in the third floor. It had a master bedroom and a living room with 2 bunk beds, a table and kitchenette. The dining table is tiny for 4 persons, so eating there was a little bit uncomfortable. The beds are good and the shower was fine.
It's perfectly located in short walking distance to the main square.
We arrived at night, and they were waiting for us to handle over the keys.
There is an elevator in the building, so bringing the luggage upstairs was no problem.
The tap water is not drinkable. (Don't buy anything at the store downstairs on the corner. It's much too expensive! They wanted to charge 5 dollars for a bottle of water...)
Remember that you can't use euro in the Czech Republic, so make sure you exchange some money to Czech crowns.
Kims Vill is a highly recommendable place to stay for visiting the stunning city of Praha. We would come back.
