Our stay in Guido’s apartment was fantastic. There is a small kitchen and a normal-sized bathroom both separated from a huge bedroom by a short hallway, so it really is a full apartment rather than just a bedroom and bath. The washing machine (no dryer) worked great. And the best feature of all is the location—although the apartment is on the fourth floor of a quiet street, you are literally about 100 meters from the Ponte Vecchio, which is to say a 10-minute walk through the Piazza della Signoria to the centrally-located Duomo. A good supermarket was only 7-10 minutes away, just across the bridge in the Oltrarno.
Guido met us promptly upon our arrival and could not have been more accommodating. He lives next door to the apartment and gave us all kinds of great tips about cafes and restaurants nearby.
