when I communicated with jan thru air b&b, I didn't except communication problem,but when we (me & my friend) just arrived at Prague almost midnight (as I pre-informed Jan) we were in big trouble because of communication problem with Jan... we were truly disapointed and very upset with him, but soon realised that Jan is nice person when we met him at apartment. his apartment is very close to the center and big enough for 4 people. his room is farly clean, shower head was half broken, but at least... it was working. his kitchen is rather good for simple job, eg) make a cup of tea or sandwitches etc... although his wifi didn't work, we could use wifi from the cafe downstairs. if anyone look for place with good location & good price, I would recommend Jan.
