We stayed at Giovanni Airbnb for four nights and it was sincerely the best place I have ever stayed.
Giovanni and Valeria were both super kind and attentive, meeting us for early check in at the train station and walking us to the place, helping us get luggage up and down the stairs, offering to show us around the local streets with recommendations, suggesting sights to see around our booked tickets/places we'd be each day, and booking us reservations for dinner and a taxi back to the train station when it was going to rain.
The house itself was marvelous, with any and every amenity we could want for, and with a history Giovanni was more than happy to explain about the frescos on the ceiling and the history of the palace. It was beautiful and relaxing and was the highlight of our vacation across Italy.
If I ever find myself in Florence again, Giovanni's Airbnb will be at the top of my list. They truly made our time there unforgettable and helped in making the city seem like it was our home a little bit too.
