1readyset2go, it depends on what you are doing. I stayed at the HGI Florence and liked it. But it was my 4th trip to Florence and I know my way around. We took the bus into the historic area and to the train station for day trips.
It was a great use of points and the staff is very good.
If this is your first trip there, I would not recommend it.
If you stay there, it is better than an American HGI. It's almost like a full service Hilton. Best of all, they have a washer and dryer in the basement to use.
