This apartment was perfect for our needs ! Very comfortable, in an amazing location (walking distance to many landmarks, museums, restaurants, bars etc.) and Nathalie was a very attentive host - responding to all queries extremely quickly in spite of the fact she was not in the country.
One thing to be aware of is the main entrance door is quite difficult to open and we initially thought our key was broken when we checked in. We informed Nathalie we were having problems and she sent the housekeeper to let us in - he showed us how to operate the locking mechanism and we didn’t have any problems after that. It does require a certain knack...you have to pull the door towards you with force then push it open and we weren’t to have known this based on the instructions for checking in.
Aside from that small issue. This really is a top quality apartment and I’d recommend it to anyone travelling to Prague.
