We stayed only for one night in Prague. The apartment offered everything we needed, it was spacious, clean and well equipped. The fan was very welcome as it was really hot outside.
The location is hard to beat, in the very center of Prague a few minutes to the Karl's bridge. But don't expect a calm neighborhood at night, we had to close the window at 4am because of drunken passengers. Parking is also not that easy, ask the host for recommendations.
The welcome was nice and patient as we were some minutes late.
Would definitely com back! Thanks!
