The house is 10m walking distance from S.M.N. station, and around 30m from Piazza del Duomo. The host is very friendly and is willing to explain you on the map all the landmarks and how you should proceed to visit them (reservations, etc).
The house itself is very cool, with a sofa bed and a bed for two people. It has air conditioner, products for showering and even some cookies! Overall it was a great experience
