We had a really lovely stay and would recommend the apartment. It looks just as nice as the photos and there were some lovely touches like a bottle of prosecco in the fridge and lots of useful things in the kitchen and utility to help you during your stay. It is in such a central location, it was wonderful to be able to walk down to the rialto market in two minutes each morning.
At the time we stayed in Aug 2022 there were works being carried out to the front of the building. We were warned about this in advance of staying, and the workers didn't make any noise so all good. I just thought i'd mention as we did wake up every morning to find workers outside the lounge windows standing on the scalfolding so had to keep the curtains closed at all times for privacy.
Also, as a few others have mentioned in the past, the appartment isnt actually in Campo San Polo but a small side street a few mins away - in case this affects your choice to stay.
