Gibby's apartment in Santa Croce Plaza was outstanding.

Gibby is a great host. She met us at the door just when she said she would. She showed us around her spacious place, gave us great tips for places to eat (with locations on a map), and communicated back and forth quickly. We had no issues at all with the apartment.
The apartment itself is vary large, with a living room up front overlooking the square and a bedroom in the rear that could be darkened completely and was immune from any noise from the square. In between was a kitchen with all of the amenities one might need, although we took all of our meals at restaurants. The bathroom was modern with the typical small, square shower. The hot water was ample and as hot as one could possibly need. Much better value, larger, and more comfortable than a hotel room.
The location is exquisite. The entrance is right on the square near the beautiful Santa Croce church, which is well worth exploring. There are three great restaurants within two blocks, including two of the best pizza places (Cucina Torcicoda on via Torta and Caffe Italiano, also nearby). The other restaurant, which Gibby recommended, is the family-owned Trattoria Il Francescano.
It is about an 8-10 minute walk to the Piazza della Signoria which has the famous outdoor statues, and the Uffizi gallery right next store. Within 5 minutes of that is the Duomo in one direction and the Ponte Vecchio in another. So you are close to all of the major sites. Florence is a wonderful city to walk through and almost nothing is further than 20-25 minutes away.
A wonderful host, terrific apartment, and convenient location. Would certainly go back.
Just a wonderful host
