Well, I only have wonderful things to say about Andrea and his home.
The house looked like a mini museum: so well decorated, such incredible furniture with wonderful pieces.
Our room was very tidy and clean. Besides that, it had many friendly lights everywhere and the mattress was very comfortable.
The flat is very close to the central station (10min or less walking). Andrea gave us, in advance, an explanation on how to get to the flat.
As a host, Andrea is a remarkable dedicated one. Andrea was able to receive us after the time scheduled, since we arrived at Florence by train in the late evening. Even at that late hour, he was kind to describe a bit about the city and what to see. He had created his own guide book about what to visit in Florence, with a map, plus a list of top restaurants. Very useful by the way.
Throughout our stay, Andrea shared with us by WhatsApp more restaurants that we could try and two vouchers for a museum visit.
I definitely would recommend it to anyone who intent to visit Florence.
A 10/10, worthy to stay.
