Marina is a great host and I highly recommend staying in her apartment.
The location is perfect, off the main tourist trails yet easy walk to all the major sights. It's also easy to get to by public transport from the airport. Around the area Marina recommend a couple of lovely restaurants.one of which we ate in twice. Also found a great bar to sit outside in the evenings after dinner just over the canal behind the apartment.
It was very hot in Venice during our trip so it was quite hot sleeping at night but think that is unusual.
Communication with Marina was spot on and she was there waiting when we arrived. (I messaged when we were on the boat over from the airport)
All in all a perfect spot to see Venezia from!!
