Davide's place has a beautiful hall in an old palazzo with rooms that are comfortably bigger than most hotel rooms in venice. I saw a review saying the bathroom was small, I do not agree: it's a standard size and has a rather large shower. The weather was rather hot, the room was refreshingly cool which was perfect!
The place is well situated in the centre, you can follow the street signs to ospedale which is the hospital in the (beautiful!) piazza San Giovanni e Paolo nearby. Rialto bridge and Piazza San Marco are close by, around 15-20 mins walking. We walked through the whole city as it's not too big and it's the perfect way to explore it's beautiful alleyways and canals.
Davide is an excellent host who explains well and makes everything simple for the guest to understand e.g. how to walk around in Venice and where to have breakfast and dine. Every recommendation he gave was great and he went out of his way to make our stay as comfortable as possible. Highly recommended.
