I've had plenty of good Airbnb experiences, but I have to say staying at Michela's place in Venice has been my favorite.
Michela's apartment is a beautiful space, ideal for a family of 3. It's perfectly located, pretty, and elegantly laid out. It has a small but very functional kitchen, which she stocked with all the essentials (pots, pans, dishes, oil, spices, etc) we needed to prepare a few meals with groceries from the nearby supermarket. And an air conditioner that was equal to the Venetian heat and humidity.
Even better, Michela herself is an awesome host! She met us en route from the train station to her apartment to make sure we wouldn't get lost, gave us lots of useful recommendations, and was just super friendly and caring towards us. Full disclosure: I've been working on my Italian, which made it a bit easier for us to communicate.
Only downside: it's a 4th-floor apartment, so be prepared for a few steps.
I'm already missing Venice, and I hope we get to stay at her place again someday.
