Very nice apartment, clean and in good condition, not at all worn-out. The location is perfect, all the major attractions are in walking distance (10 minutes to the Piazza Signoria and the duomo, 5 minutes to S. Croce), but the house is in a quiet side street and our sleep was not disturbed by noises. Although the apartment corresponds to the pictures, it is a little smaller in reality as I had imagined. It was perfect for two persons with the luxury of a second bathroom, but I would have felt it to be too small for two couples. The kitchen is sufficient for preparing breafeast and smaller dishes but not for serious cooking (two hobs only, a microwave, but no oven.) The large terrace is just wonderful.
I didn't meet Giacomo personally, but his representative, who checked me in, was very nice and helpful.
