I had a wonderful time at Jiri's flat. It's very close to Charles Bridge, but also is quiet and calm. The windows look out onto a park, and so you have all of the advantages of being close to everything in the city centre, while feeling you're in the country. The bed was comfortable, and the facilities were all great. The flat has a small washing machine that was very useful! While I didn't meet Jiri he was very helpful via email. His brother let me into the flat, and showed me good places to eat on a map. I would highly recommend Jiri's apartment.
