Really lovely stay for us! Everything was clean and the apartment is gorgeous and not humid like many. I would stay again for sure, and hope to soon.
Few things to keep in mind, it feels like your staying in a luxury hotel room, hosts will not be there to greet you and give you tips on restaurants or good bars, etc. Mentioning this only because some people like that aspect of Airbnb ! With that said, hosts were communicative and again, the apartment was stunning.
Also keep in mind, you are in a quiet part of Venice. 10 minutes from San Marco, but the rest of the city is 30 and 40 mins walk. You will be very close to the Biennale however, so depends what you want to do !
Would stay here again.
