We stayed for 3 nights. Location is in walkable distance from all main sights (if you are into walking): we never used metro/buses, though the station was nearby. There are several rooms in the flat, you might be able to choose whether you'd prefer view to the street with occasional noise in the night, or a quiet room facing the yard. Communication with host was easy. Thanks to Tony&Liz for hospitality. We found everything we needed for a comfortable stay.
