Great location & fantastic communication. The host manages a tour company which is in the building next to the apartment so every detail was conveniently handled.
The location is a short walk away from the train station near the Duomo, very convenient for sightseeing & surrounded by tons of restaurants. The apartment itself is up one flight of stairs so if you have if you have large heavy bags, you need to be prepared. We only had carry ons so it was ok.
The kitchen in the apartment is tiny but the bedroom & front room are spacious. There was a fold out sofabed in addition for more than two people.
Marco & his colleague, Bianca were excellent with their customer service. I would definitely recommend Marco's place in Florence.
