Pros: The location is great for the key touristic parts of Prague. The flat itself has lots of character and what looks like history. It's spacious and has everything you need for a short stay in Prague.

Cons: We didn't see the host at any point - we were greated by his (lovely) friend but who speaks no English or German so had to communicate with hands and sounds!
We found a used condom wrapper right under the bed from (we assume) the previous visitors, which could awkwardly be the guy from the review below mine :D..!
Considering they would have been charged a good amount for cleaning, it was really off-putting. The bathroom looked clean overall but on closer look the seat was not clean and there were hair in the shower from previous visitors. There was also something sticky on the floor by the kitchen units - we arrived at 7pm so there would have been plenty of time to clean the place!
Discovering this made us uncomfortable and question how clean anything was in the flat!

Overall - We really liked the flat, the location and the facilities. We were disappointed by the lack of cleanliness in key areas, however, as the flat had so much going for it and really hope the host invests in proper cleaning.
