The apartment is very clean and well located. It's great to be on a busy street and near a canal. It really feels like you are in the heart of Venice. There is a vegetable market, butchers, bakery, coffee shops very close by. The neighbourhood feels "lived in", not only a tourist place.
We stayed here in January, with the windows closed all the time. Despite the fact that the street is really busy, it does quiet down at night, but you will hear noise early in the morning and throughout the day.
The two things that we were disappointed with were the sparsely equipped kitchen (no wine glasses, cheese grater, vegetable peeler, good knives, staples such as salt, oil etc) which is frustrating when you want to cook with the wonderful local ingredients. Secondly, the wifi connection cut out frequently.
Our host, Roberto, was very friendly and accommodating.
