Would stay again any time. Nice host, provided useful touristic info including maps; central location, view of San Marco Campanile just over the roof tops; safe baggage storage after checkout; hot water and heating worked very well; beds were comfortable; gas cooker has 4 flames, and there are enough pots and pans to really use it; brand new 6 kg washing machine with a super fast cycle- just bring your own detergent. Unique wall paintings, one of a kind- this place really has a bit of Venetian theatre old world charm.
However, this is also a really old house: one needs to be fit to get up all those steep stairs, and not too fat, or the bathroom and the kitchen sink area will be uncomfortably narrow. Also, the ceilings are low: 2m or so. If that is fine with you: go for it!
And if you want to cook: there is a great little butcher shop right around the corner, and an expensive, but very good deli down the street, and 2 supermarkets at the Canale Grande. Plus the big market right across Rialto bridge.
