Four of us spent ten days in this apartment and would go back tomorrow if we could.
The sense of space, both inside and out, was delightful - and rare for Venice. We had lunches on the balcony on sunny days, with a wonderful view of Campo San Polo, and felt perfectly cosy indoors on rainy days. Also, we felt we were in a home, and not just a rented apartment, which is how Airbnb started and which we still value as its ethos.
Three small snags: the kitchen is only for one person to work in and then that person must be used to working in limited space (We ate mostly salads and easy pasta - delicious!)
The double sofabed on the floor of the mezzanine we found perfectly comfortable but - when we went to bed it meant the large living room was essentially unusable if we were to have any privacy. Also, to use the bathroom during the night, you have to go down and back up the wooden stairs; not a problem for us but perhaps for anyone who has difficulty with stairs in the middle of the night.
Finally the two single beds in the bedroom on the ground floor are in a room that opens onto the pizzeria courtyard. Our friends closed the the windows and used the air conditioning. We need to be able to open a bedroom window, so opted for the living room mezzanine.
All in all, in spite of the potential snags, we had a wonderful time and recommend this accommodation heartily.
