Nikita (the host's live-in-the-property son) picked us up in busy piazza San Marco and took us to the apartment, which is in the very heart of Venice. Close to everything, yet it was not noisy! The room looks just like the pictures, and there was a mobile AC unit as the wall mounted AC was not yet working. I don't think it's mentioned on the listing but the apartment is on the top floor, which was OK -but not easy for my mother.
They were nice and accommodating, the place was very well cleaned and I appreciated the mini fridge in the common area to keep drinking water cool. Breakfast offer is minimal so bring your own or ask them for a decently priced caffé bar (some of the bars nearby are tourist traps!!). Nikita's recommendation for dinner nearby was great, well priced and tasty :) Value for money is good considering the location, and the fact that Venice is very expensive in general.
