I didn't get to have much contact with Kristyna, but Anna was a wonderful host even if we didn't actually get to meet in person. She was always friendly and ready to help whenever I needed it. The building is in a great location, right next to a subway and tram station in a very central part of the New Town zone of Prague and with lots of shops and restaurants around, and the room is incredibly spacious. The one thing that didn't make my stay perfect was the fact that the mattresses (yes, there were two beds in my room lol) were way too thin and the bed structure was also too close to the floor, so watch out especially if you have back problems of any kind.
