This Airbnb is very centrally located, close to Ponte di Rialto. Right below the appartment there is an excellent (and only slightly pricey) restaurant in which we were lucky on one evening to get a table without reservation.
With respect to the appartment itself, we had a pleasant stay. It was clean and the bed was comfortable. There was a tourist map for us which helped with orientation. The kitchen was a bit spartanic and there was no oil nor spices for cooking - I am used to finding such basic things in Airbnb appartments because nobody would buy them for a short stay.
Prices were immensely increased for the week-end, I would recommend to only visit Venezia during the week. Then, however, I would definitely stay again in this airbnb.
