I stayed two nights here in Laura's flat. It is shared with three other rooms, and two bathrooms are shared as well. It was clean and tidy, and she provided some tips on the local activities.
The location cannot be beat. It is steps to the river and the duomo. Fantastic location.
It's on the top floor, five stories up. It's a climb if you're hauling heavy bags up the stairs, so be prepared for that.
Laura was a very kind and gracious hostess. I would recommend this place to my friends.
