The medieval house was all we needed for our Florence 6 days stay. Very close to Uffizi Gallery, Piazza della Signoria, famous Ponto Vecchio with the grand view of Arno, Oltrarno district, Duomo, Basilica de Santa Croce, Academia... you name it... Everything is reachable within a 20 min walk. Even though its located on a very busy street with lots of eateries, the apartment is very quiet, especially at night as it facing away from the streets. It has a lot of character and is a feast for the eyes, with a diverse art collection lining the walls, and lots of bookshelves.
The only minor issue we had was that wifi was not always reachable from the opposite end of the apartment.
We didn't meet the owner, Guilio but he was just a text away. He had a list of suggestions in the apartment which was also emailed to us before arriving.
We took a taxi from the Firenze SMN Railway station which normally was just a 5 min drive, but with so many people out on the streets sharing it with the cars and horse carriages it might take up to 15 min. Taxis are hard to catch in Florence, and there are only two ways: calling the taxi agency (which did not work in our case) or waiting for it in the designated areas. Just be aware of the taxi situation in Florence.
