Our stay was in venice was wonderful. The apartment was very cozy and tucked away on a street away from a lot of tourist traffic so it was also very quiet and peaceful. Also the little outside area was really nice to sit at night.
The space was also a good size for my wife and I, and I would say it would also comfortably fit four people if you wanted to travel in a small group.
Giacomo an Giulia were amazing with communication and made getting into the apartment very easy--we met with Giulia who took us to the apartment and she was wonderful with helping us with how to get around the city.
Overall a great experience for me and my wife and if your looking for a nice, quiet place in Venice I would go for it.
