The studio was amazing, very comfortable, and Settignano is a beautiful little Italian village right outside of Florence.
I never got to see Luca, but I followed all his instructions and didn't have any problems finding the studio.
The only thing that we couldn't get to work according to the instructions was the wifi, and unfortunately it never got fixed during our stay.
I highly recommend the studio for people interested in visiting Florence that are looking for a real Italian experience (take into consideration that the wifi might not work).
