It was a super stay at this house. The location is super convenient, very close to the museums, state opera and the train station. The old town was very walkable (we walked everyday). There are 24x7 shops just out on the main street, and an awesome pizza place as well. There is a pub right across the apartment! ;-)
On the first day we met Emil, and he was super helpful in terms of telling where to go and what to do. We did most of those things, and they were really authentic Czech.
The house was exactly how it is shown in the photographs.
All in all, a very pleasant stay. We would highly recommend this to other people travelling, especially if you're planning to see this city how it is supposed to be seen, walking!
