Great apartment, fully furnished. Off the main path so it is close to everything but quiet and private. The address listed on Air BNB is not correct and we had some trouble finding it. They say that it is only a 15 minute walk from the train station, but unless you are a triathlete you should plan on more like 30 (if you know where you are going). It is only about a 3 minute walk from the San Stae vaparetto stop so once you find it the apartment it is very easy access.
The facilities are great, clean, well equipped, and the Mario folks were very helpful with good communication.
