Klara's apartment is spacious, nicely furnished, and fully equipped. There are two full bedrooms, with queen size beds. One room has an ensuite bathroom that has a shower and sink (no toilet), the other room is a lot more spacious and has a bed, and two chairs. There is a separate toilet, and a full bathroom near the main entrance. The kitchen is huge and is fully-equipped. There are a lot of windows in the apartment but we had the curtains down the whole time because the building is built in such a way that the neighbors' windows are very close, which provides no privacy.
Keep in mind that there is no elevator in the building. But the location is ideal. It is only a few minutes away from the main train station, and the buses to the airport pass by that station. It is in a quiet neighborhood and close to major shopping streets, and about a 10-minute walk to old town and Charles Bridge.
Klara is very responsive and provides helpful information. My group of three lady friends and I truly enjoyed our time in Prague and our stay at Klara's place.
