We didn't meet Luigi, but were put in touch with a local contact who met us as planned at the vaporetto stop and took us to the apartment.
The location of the apartment is fantastic, overlooking a canal and bridge, just as in the photos. Great location for getting around the city as very much in the heart of it.
The bed is a sofa bed, which was just about comfortable for 4 nights - the mattress is quite thin.
The bathroom and kitchen are fine and it was good to have a "proper" kitchen to do some cooking.
Overall the apartment is great value for a stay in central Venice and our experience was made easy with straightforward communication from the local contacts. Recommended for a short stay.
