Guido was a great host. He meet us at the apartment when we arrived, showed us how everything worked and checked in with us while we were there to see that all was going well. He also called us a taxi when we left.
The apartment is spacious, it has comfortable beds, a nice kitchen and a nice balcony. It has AC which is must for Florence in the summer. It also has a washer and a drying rack for laundry.
The Santa Croce area is nice, it is close to all the sights and the area has good restaurants and wine bars. In fact Quelo, a friendly wine/cocktail bar a few doors down had a good setup where in the evening if you buy a drink you can eat from their excellent selection of cous cous and pasta salads.
We had a great stay at the apartment and would stay there again.
