As a Venice addict, I have been a various hotels and airbnb there, and think this must be my absolutely favorite place. The flat is spacious, elegant, artsy and stylish with a mix of period architecture, design furniture and contemporary art.
The kitchen and bathroom are impeccably finished, although being so central, there are so many places to go for breakfast, lunch or dinner, that we didn't eat in much.
The location is absolutely perfect with the Ca Rezzonico vaporetto stop very close and without any bridge to go over. There is a very cool bar just next door, and a grocery store delivered by a barge daily, how much more Venetian can you get?!
Finally check-in and out is very well organised and directions very clear, making the process as smooth as could be.
In brief, can't recommend the place enough!
