This was a great apartment for two couples, the location is excellent, close to a beautiful square and all the main attractions yet still feels like you are off the beaten track.
Apartment was clean and well maintained, potential for noise issues from apartment above, every footstep and furniture movement clearly audible, we were fortunate the couple above kept civilized hours. Also construction noises periodically from the adjacent building.
Mosquitoes are a bit of a plague in Venice, we kept all the windows closed, burnt citronella outside and sprayed ourselves religiously to keep them at bay. The ac worked well to keep the apartment comfortable.
Host was excellent, picking up and dropping off keys went well, problem with no hot water solved within a couple of hours.
