We really enjoyed our stay at Paolo's apartment. It was clean and well-furnished, and Paolo made an extra effort to meet us at the boat station, help us with ourbags, and give us many tips and suggestions. Location was great, very close to major attractions like St.Mark's basilica and the Doge's Palace, and right around the corner from many cafe's and restaurants.
One suggestion would be adding screens to the windows, because there are a lot of mosquitos around at night. There is also sometimes a slightly unpleasant smell coming from the water in the canal that can come into the apartment, but that is part of the area and the smell isn't coming from the apartment itself. Can also be a bit noisy sometimes with supply boats going by in the early morning
The other major complaint is that the WiFi barely worked; there was a WiFi connection but it almost never worked to send or receive.
Overall, we enjoyed our stay and had a great 2 nights in Venice
