The apartment is fine located - the center of the Old Prague, you can reach easily by walking all nice places - The National Museum, The Watslav Square, etc... The apartment is actually biger than it looks on pictures. It's more than enough for two persons, there are some extra places for the other two's.
Beside of this, Jan (the host) is very nice person. He is very quick resposnsible, he's doing all his best for solving any problem you have... After check out time, when we left the apartment about an hour later we suddenly found out that we've forgotten our photo camera in appartment. I've called Jan, we returned - Jan was sitting down at the stairs waiting for us with that camera...
Highly recommended! Really god deal for such a price!
