We missed the last train from Venice to Florence (where our Air BnB was) and Gian Maria was a lifesaver and accepted our reservation at 9:30 PM! He didn't expect it, of course, but responded immediately, got us situated and even sent voice recordings to teach us how to set up the extra beds because it was prepared for the next guests at the time (who had two fewer guests than us). It could not have been better with Gian Maria. If you want a place to stay in Venice with a great host, Gian Maria will help you. The A/C needs to be turned on early in the day and the doors of the bedrooms should be kept open so that it cools them if you like it that way. Thank you Gian Maria!
