Stefania was fantastic. Best experience we had in Italy. She was the only one that provided very useful information about the city and gave us a detailed map.
Another great thing she has a portable internet device, so you can walk around Venice with it and have internet. Major plus.
The place was clean, very modern, with comfortable bed.
The only thing there was no AC, and it was so hot in Venice while we were there. The fan was provided though, so it was pretty comfortable to sleep.
Great location as well. Very close to the grand canal. Walk able distance to most attractions, stores and restaurants.
Very highly recommended.
