Daria and Ilaria's place is in a wonderful location. The only downside is some bar noise in the evening, especially in the room facing the street. The location more than makes up for it, however. You're out of the touristy area of Firenze and can stroll down quiet streets. There are cafes, restaurants, and bars nearby.
The house itself is lovely, with everything you may need, and it is perfectly clean to boot. Would stay again.
