Everything went great at Mark's apartment we were received by one of Mark's receptionists and she was very kind. The location is good if you like to walk the city and also if you prefer to take the Tram or Metro. The only critic I've is that the bathroom doesn't have a door, only a curtain that separates the bathroom from the bedroom. Even thought the apartment is huge for 2 people and very convenient if you are staying a few days in Prague.
