Really close to the city centre, about 10 minutes walking. Ground floor, good for handicapped people (just in case). It's in a quiet district, car park is just 2 minutes away from the app.
Everything is OK, the housekeeper is there every morning around 9 and gives all kinds of tips to make your stay in Prague as good as can be. Free city maps available. There is one kitchen for all guests, but you don't really need it when you are there for a couple of days only. Good restaurants everywhere and close to the app. too. Karlov bridge is 15 min. by foot and Prague castle maybe 25 min. The apartment is new and clean, you don't need any keys (cannot loose them), just a 6 digit code for all doors.
