We had a great stay at Riccardo's apartment in Florence. It's conveniently located--a stone's throw away from the Ponte Vecchio--and a great experience. The apartment was clean and as described (bigger than I expected!), with fresh linens and towels and spacious bedrooms. Despite the busy nature of Florence, it was very quiet at night.
Riccardo met us in person to check us in and was gracious and helpful. His restaurant recommendations were very good. We went back twice to both his recommended sandwich shop and trattoria.
I would definitely stay here again.
