We stayed in Nick and Jenny's place for 3 nights in early September. There was someone waiting for us to hand over the keys and answer questions. The apartment is very clean and nice, it seemed recently remodeled. The sofa bed is very good and can sleep two adults comfortably, though we did not need that given there were only two of us. there are extra bed sheets and towels and a washing machine so you can wash them if needed. Location is right next to the old square and Charles bridge so you can't be any closer than that. The problem is you are in the middle of the action and noise from the street below will keep you awake all night if you need to leave the windows open (which you have to in warm weather). Closing the windows will keep the noise out. In general we enjoyed the place and appreciated it's cleanliness and location. Nick and Jenny were easy to communicate with and were accommodating with requests in checking and check out, so many thanks to both.
