My sister and I went with our partners to Venice for 3 nights.
Elettra's husband Diego met us at the Vaporetto stop and walked with us to the house and explained things about the house. He was also very helpful in advising us on a couple of touristic sights. Elettra and Diego were always quick to respond if we had additional questions during our stay.
We had a nice stay in Elettra's home in a quiet neighbourhood near the waterfront and just a few vaporetto stations away from the centre. The bakery and supermarket were just a short walk away.
The possible downsides are the relatively small beds (max 140 cms) and the noises drifting up from the streets early in the morning (e.g. garbage collection, barking dogs).
The kitchen was cozy and clean and there is space to eat a meal with 4 people. The bathrooms were just big enough and clean. The absolute plus for us was that there were two separate bathrooms.
We certainly would recommend this appartment!
