We had a wonderful stay at Marusca's place. The view is beautiful, and you can't beat morning coffee or evening drinks on the terrace. The location is perfect for those who like convenience and a lively neighborhood - there are restaurants, cafes, a grocery store, and shops (clothes, jewelry, antiques, art) right outside the door. The Plaza Signoria and Ufizzi are just 5-10 minutes away, but it quiets down at night. For those who are directionally challenged, the location at the end of the Ponte Vecchio makes it hard to get lost. And Marusca's place feels like a retreat from the hustle and bustle below.
Marusca was great - we were unsure of our arrival time, driving into the city (as an aside - something I would not do again!), and Marusca was flexible and made it easy. She has a great assistant (whose name I forget) meet us, and he helped us park the car in a garage just down the street. We were also able to check out and store our bags there until our departure later in the day.
Marusca was great in responding to anything we needed. It felt like she was a professional - everything was as described, seamless, and easy. Cannot recommend this place highly enough! I would stay here in a second if I go back to Florence.
