We had a lovely stay in Florence. From booking through departure, we were always in good hands.
Gentiana (Artan's assistant) helped us with transportation, booking of tours, recommendations, etc.
The location is outstanding! You can walk everywhere. We had Artan pick us up from the train station (for a reasonable rate), but if you're comfortable finding you're own way, it's definitely walkable.
We hired Artan for an all day tour of Florence, and it was great.
Only issues with unit - it really only has one shower, and the back half of the apartment (kitchen & one bedroom) doesn't have AC. We made it work. It was quite hot while we were there, but with fans, windows open and the awnings, it wasn't bad.
Overall, a beautiful stay.
