The best feature of the place is its incredible location, the very center of the old town, three to five minutes walk to Domo and Piazza Della Signoria.
The place is recently renovated, clean and neat, provides all the necessary things for a comfortable stay.
The hosts, Elena and Gabriele, are very attentive and flexible, though the checking out time was 10 AM, they still let me leave my luggage till 5 PM.
I'd like to come back to this place next time I travel to Florence, and I would recommend this wonderful space to everyone.
