A group of 7 of us were staying in Prague for a work-related conference, and Jan's apartment was a great solution for us to stay together at a very economical rate. The first thing to say is that the apartment is very spacious and was absolutely perfectly clean. When we arrived the cleaners were still in and we saw first hand how thorough they were. My correspondence with Jan was perfect; I had a problem with my phone on arrival, but when I managed to get through to him he was there in 5 minutes. He explained everything and was very kind and polite. All my colleagues were equally happy with the flat which was 1 minute away from the metro and our short commute (2 stops) to the Prague Congress Centre. The only problem we had was the apartment was pretty warm for the first couple of days because Prague had had 40°C the previous week, so the building was still hot and humid and the AC struggled to cope. I'm sure that would not be a problem except during the height of summer and it was fine for us after a couple of days. The other thing to note is that the only cooking facilities are kettle, toaster and microwave. That is not a problem as we would have eaten out anyway (Prague is pretty cheap), but if you want a fry-up for breakfast you won't be able to.
