We had a lovely time staying in this apartment for a week in the winter. The apartment was very warm and cosy. It was located near to a small supermarket and a few restaurants. The kitchen was perfect for preparing our own meals when we wanted to stay in. The location was perfect if you want to be out of the main bustle of the centre, with about a 15 minute walk to St Mark's Sq. If you don't want to walk that far, there was a vaporetto stop at the waterfront. It was also very conveniently located near P. Roma (the main transport hub with buses to the airport, a train station and more vaporetto routes) - once we stopped getting lost it was a less than 10 minute walk.
Some local information was provided in the apartment (a walking tour book proved to be very helpful!) and although we didn't require any help during our stay, we felt we could easily contact our hosts if we needed to.
We really loved having this place as our base while exploring Venice!
