We (two adults, two children) spent two nights at Irene & Alain's place and had a great time. Everything was as described, and Irene received us at the arranged time and place. Our hosts had provided us with helpful advice beforehand. The apartment is in a great location, right behind the Duomo, and allows you to explore the center of Florence on foot. As it was a cold weekend, we were especially grateful for the well-working heating system.
