Great host who helped to arrange transfers to and from the airport and allowed us to store our cases after check out. The apartment was very well located near the Old Town Square- we were able to easily walk to all the locations we wanted to visit. We were two girls and we both felt completely safe walking to and from the apartment late at night.
The apartment is up a flight of stairs, with an extra few stairs from the kitchen to the bathroom- no trouble for us, but might be tricky for very young or elderly guests.
The apartment was clean with some basic kitchen supplies- although I'd suggest stocking up on any snacks at the nearby supermarket. Good selection of guidebooks for the local area. Lovely comfy double bed and a very quiet bedroom which led to some great nights' sleep. The shower was hot and had good water pressure.

Overall, we had a fantastic holiday in Prague and found that the flat was a perfect base for us.
