Mauro's place was great! It has a very good location, almost everything is within a 10 to 15 minute walk. We paid 10 euros each way by taxi to the campo di marte train station when we traveled to and from Rome.
The apartment it self was nice, with new appliances and plenty of dishes and linens. There was also a washer, dryer and hair dryer.
The apartment is on the second floor, (two flights of stairs) and has a small elevator.
Our host's father, Guiliano, met us upon our arrival and went out of his way to make sure our stay was good. It was a pleasure to meet him as well as get tips for our stay in Florence.
This was a very comfortable place and I would recommend it to anyone.
