Location is amazing! Right across the market, where you can eat and shop local delicacies.
The main tourist attractions are in 5 min walking distance.
Apartment is old, but neat and clean with all the necessary amenities.
Keep in mind, with the location come the people, so you can hear chatter on the street from early in the morning.
All in all, great and charming place to stay for a couple of days sightseeing in Florence.
