Possibly the place with the best view in Florence - directly overlooking the Piazza della Signoria and the Palazzo Vecchio.
My wife and I stayed here for 8 days and loved every minute of it. Donatella's place is superb with the listing being accurate. We didn't get to meet or speak with Donatella but her person checked us in efficiently and all email queries were answered promptly and issues addressed by Donatella. She was particularly helpful in organising printouis of tickets and getting some minor issues fixed.
If at all there are a couple of downsides they are:
1. The apartment is on the third level and there is a flight of stairs upto one level before hopping onto the lift. Seniors and those with heavy bags to note.
2. There is no laundry facility in the aprtment. But there's a coin operated laundromat a few minutes walk away.
Apart from these, the place is fantastic- large, right in the heart of action and walkable to all sights.
Will definitely stay here the next time we're in Florence.
