This is a great place for a family of 3-4 to use as a base for exploring Venice, made even more so by Massimo's excellent hosting and (judging from when we stayed in February 2022), very competitive pricing. The only caution: guests need to be able to navigate a couple of sets of stairs - without or with luggage help from the inexpensive porters based at the nearby train station (we were DIY and did fine). And once the up the stairs, there are great views of Venice.
Both bedrooms are spacious (one with a queen bed, the other with two singles), as is the bedroom. The central eat-in kitchen includes a counter with chairs plus a small living room section and is thoughtfully provisioned (including with nespresso, crackers -and Nutella).
The final bonus is Massimo himself. He is kind, highly responsive, clear, and has prepared personalized recs for seeing the sights and eating out. It's no knock on good hosts to say that he in truth one of the best.
