Had a great stay in Prague in the harry potter house. We really enjoyed ourselves and this apartment had everything we needed, even things you wouldn't normally expect like toilet roll and tea/coffee.
The beds were all comfortable we slept really well - it is a quiet area. The location is great, I'd recommend visiting bars and restaurants local to the apartment as they were all excellent. It only takes 20 mins to walk anywhere touristy you'd normally want to visit.
The hosts were great at communication, giving us multiple ways to contact them and really fast responses. They were friendly and made us feel at ease on arrival.
