We had an amazing time at Stefano's apartment. My family of six had plenty of room (2 adults in one bedroom, 1 adult and 1 child in the other and the last two children on the pullout couch in the living room). We appreciated the extra touches like a greeting bottle of wine, slippers to wear around the marble floors of the apartment, children's blocks and coloring supplies, and all the clothes line clips to dry our laundry - the patio off the large bedroom was perfect for hanging laundry. We had no issues with water pressure or the temperature of the water. The apartment was very clean and well supplied. Stefano and his team were incredibly communicative, responded right away to all concerns and were very pleasant to chat with.
The view is phenomenal and we got to spend lots of time taking in Venice from above. The one small hangup was that the lift was out of order during our stay, but actually grew on us as we appreciated the extra exercise and authentic experience of staying in a home built during the 1600s.
The location was amazing, right by the Grand Canal, excellent restaurants, our favorite gelato place (Fantasy Gelato) and coffee. It was easy to access everything either via vaporetto, private water taxi or walking.
I would definitely stay here again if we find ourselves in Venice in the future.
