As we didn't know the city, at first we thought that the apartment was too far from the touristic part of the city, but we were wrong. If you don't mind walking it is a lovely way through a very nice park to the Prague Castle.
The apartment itself had everything we needed and more. The details at the dinning table were very pretty and there was a wide variety of kitchen tools that made it easier for us to cook at the apartment. There were also the basic cooking ingredients (salt, oil, sugar...).
Also Katerina offered us facilities to leave our luggage after the check out while we made the most of our remaining time. She also provided us information about what was the best way to go to the apartment from the airport.
All in all, it was great. Totally recommended.
