The apartment is very nice, it has three very big rooms and two bathrooms, the kitchen is very spacious too. Location is amazing, you can reach any major sites by foot. The apartment was clean and just as pictured in AirBnB.
The staff that received us was amazing, they were very helpful and gave us a lot of information about places to go and things to avoid. When we needed help they were always available by phone.
The building in which the apartment is located is very old, as all buildings in an historic location are, thus the access to it and location and operation of the elevator were a bit challenging on first arrival. A more detailed description on this would have been helpful and if we would have arrived at night then this would have turned into a bigger challenge.
I would definitely come back to the same apartment when in Prague.
