We stayed at Donatella and Alberto's place for a week while in Florence and had a wonderful time there.
Pros: BRAND new, beautiful, remodeled apartment and everything in it, too! Super clean. Had everything you needed, plus more, including extra (large and fluffy) towels, laundry soap, coffee for the week, a bottle of wine, great wifi, comfortable bed and lovely linens. It is very open with high ceilings and felt spacious. Huge bathroom with a good lighting and big mirror. Super quiet in spite of the busy street. Two A/C units. Elevator. Grocery store and restaurants downstairs in the same building. Right across the street from train station, so super easy to get to (plus buses right in front, too). Walking distance to everything. Excellent and prompt communication!
Cons: busy right as you walk out the door (but never any issues and we felt completely safe at all times, so not a bid deal). No view from the balcony. Only local channel TV.

We thoroughly enjoyed meeting Donatella and Alberto and happily accepted their invitation to join them on a wine tasting, where we also met many other family members. All were super nice and we loved that we got to see/hear more about what life in Firenze is really like. We have stayed in 21 Airbnb's this year and this is definitely one of our favorites. I would 100% recommend staying here!
