We stayed in this apartment for 5 days in Florence. We enjoyed out stay - now for the pros and cons:
Pros - great 2 bedroom 2 bath with quaint florentine architecture. The location is unbeatable 4 mins to Dumo and within a 12 min stroll to all other major sites. All the amenities in the apartment are accurately described. The checkin process was great - Claudia the host was gracious and gave us some tips on restaurants. Check out was also easy. The location has numerous restaurants within a 4 min walk and the mercado central is bang opposite.
Cons - location is both a pro and a con, its right on the leather market street that is closed to traffic from 8 am to 8 pm. So if you have luggage you have to roll it along from the end off the street. If you happen to need a cab same applies. The street noise is bad if you keep the windows open but we closed them at night and had no issues with noise as the windows were well insulated. The apartment is on the 1st floor (for us in the US its the second floor), you will have to walk up about 20 stairs - no elevator.
Overall we had a great time staying there, we were 5 adults and it was very comfortable
