Leonardo is a great host. I visited the flat as the first one after the lockdown. He was perfectly prepared regarding all the new hygenic criteria and I felt absolutely safe.
He was absolutely friendly, open and when I had a request he answered directly to my mails. The flat lies in the center of the town, just an 8-minute-walk away from the cathedral. There a shops and restaurants direcly next to the house entrance. At night it is absolutely quiet and the huge balcony is a great place to stay and hang out.
Florence is worth a visit right now more than ever before because the are only few tourists and all the sights are reopening just now or have already. Please book for the cathedral tickets over the internet in advance, visits are already booked out unit august due to Covid-19-regulations. But there is so much other stuff to visit...
