This was my first experience of renting via Airbnb and all went very smoothly. Mario's apartment is in an ideal and untouristy part of Venice but within easy reach of all the sights and with a magical view of a canal. We were going to the Biennale which was only 10 minutes from the flat.
Mario was efficient, friendly and helpful.
The apartment had everything you might need for a short stay in Venice and was very clean and well cared for.
I can strongly recommend it.
