Room was good as the pictures and the host was nice and considerate. Having lived in Venice for many years, I know how difficult it is to find a reasonably priced accommodation in such a central and ideal location, let alone a single room.
The only cons flagged by other users, such as steep staircase etc, are a natural consequence of staying in a Venetian house rather then a hotel.
When of I booked this room(low season), the price was considerably lower than hotels so this is definitely good value.
Als, while stairs might be steep, being on top is always better both because and the view and because the air is dryer - lower floors in Venice are a nightmare.
Overall very good stay, would come back!
