We enjoyed our stay, the owner communicated well and promptly, the place was really nice and clean.
The only downside were the mattresses, very soft, not very comfortable and lack of Aircon. During the hot summer days as Prague is getting more and more of, the temperature in the flat goes too high. However, the flat wasn't advertised as having Aircon, so can't really complain about that, just something it would benefit from if it had one. Otherwise very pleasant stay, would come again.
