Piero is a wonderful host and the apartment is really nice. We arrived with delay and he patiently waited for us, then we missed the stop and he sent one of his colleagues to pick us up from the other stop so that we don't have to come back. The guy who picked us up, Paolo, was very nice, gave us some little info of the city while taking us to the apartment and then all the necessary information, even gave us suggestions where to eat.
The apartment is very close to the St Marco square, not even 5 min walk. The view is amazing as well, just like the photos. Very clean as well and has all the necessities, in both the kitchen and the bathroom. We were there only one night and were very happy with the host and the apartment.
