Jan very graciously accepted us at the last minute - the same day we arrived in Prague - and the apartment was very well located. We had to wait a bit to be let in, but by and large, meeting up was easy. The apartment itself was fine, although it didn't seem remarkably clean and we were missing some bed sheets (there was just a mattress cover and a blanket). I'm not sure we would stay there again but it was fine for our quick visit.
