We've really enjoyed our week long stay at Nicola's place during our trip to Venice this January.
The apartment is very nice, located in the very center, but the street itself is a dead end, facing a small canal, so it's quiet.
The flat has everything you might need to make your stay comfortable. (save for TV, which is no problem for us)
Nicola is wonderful host, who helped us with directions, local shops and restaurants, as well as some recommendations and was kind enough to meet us at Vaporetto stop to show us the way to apartment.
The only thing that you might want to look ahead, it's the fact that during one morning of our stay the water from the small canal flooded the little street on which apartment is located. High water was gone in the afternoon.
I guess that's Venice for you, come prepared :)
We highly recommend this place to anyone who wants to experience this wonderful city at it's fullest.
