We stayed for 5 nights at Jan's place in Korunni st.
The apartment is fresh, fully equipped and clean.
The location is good for arrival from Praha central station (3 stops by tram) and from the old town (4 stops on subway) - may be not in a walking distance but rather comfortable.
The supermarket Billa is just in several meters from the courtyard door.
Communication was smooth, Jan is a very attentive and helpful host.
Highly recommended.
