The apartment is really neat and clean and exactly as advertised. It's a nice place if you are planning on spending most of your time exploring the city of Prague. Considering that there is no sofa and TV, you will need to find your entertainment outside of the apartment. The apartment is very centrally located on the 4th (and top) floor in a busy traffic street. Since it is top floor, it can get pretty hot inside. Opening the windows will help, but it will also allow the street noise to come in.
Concluding, Nathalie is a very friendly host and she gave us her recommendations on cafes and restaurants in the city.
