This is a really interesting place to stay. Location was great for us, as Venice is a very small city, and there were lots of shops right nearby. The apartment is a good four floor walk up in this old "palace" (in Venice, that basically just means an old apartment building with high ceilings). The hosts were very nice, and helped us reserve a porter for our last day, which we had not thought to do. The view from the kitchen windows of Venice was great as well.
However, there were a couple of issues. First, the beds and pillows were extremely uncomfortable. Ordinarily, I wouldn't complain about this as I can fall asleep virtually anywhere, but none of us 5 slept well. The pillows were like stacks of cardboard. We were also only given a couple of rolls of toilet paper, and told to go to the supermarket to get our own. When we objected, Giacomo did send over some more very quickly. Not a dealbreaker, but it still felt like there were corners being cut. Also, there were a few paper pouches of shampoo for 5 people over 3 days, and very weak water pressure in the shower.
Also, and this may just be a Venice thing, but the electricity short circuits if the air conditioners and washing machine are on at the same time. We didn't even have the lights on! I understand it's an old building, but this was irritating.
Still, we had a wonderful time in Venice and would still recommend staying here as a good value.
