Matilde's place is awesome! I've been looking for a place with 5 real beds (traveling with my sister, 2 teens and my mother). The apartment has 2 bathrooms which was really great. Spacious living room. We made our own dinners in the equipped kitchen (my sister loved the pasta sieve built-in in the sink). The terrace with roofs tops views is really lovely.
The house is an old palace with inner yard. The elevator was helpful with our luggage (so we had only few steps and not the whole 2 stories up). We used the house private docking in the grand canal both when we arrived and when we left (late and early flights - we took water taxi to and from the airport).
The location is really great (not exactly where the map of airbnb shows - more to the west): very close to stops of waterbus number 1 and 2, walking distance to the Rialto bridge and San Marco square, in a quiet area.
Matilde is a very helpful host. Good communication both before and during our stay. Her local tips are much appreciated.
We enjoyed our stay very much and we'd definitely highly recommend it!
