Our stay at Alberto's flat was wonderful! Alberto had someone meet us to show us the flat, and answer any questions we had. They even had a complimentary bottle of wine waiting, which was a very nice gesture!
The flat is perfectly located close to the Duomo, shopping, the Uffizi Gallery, and many great restaurants and trattorias. Alberto provided a great list of shopping and restaurant recommendations to keep us out of tourist traps. The flat is on the third floor, and there is no elevator, so you must carry your bags, but we did not find this to be a problem. The flat has a nice two person balcony with table & chairs for a morning espresso, or evening glass of wine, while taking in perfect views of the cathedral and bell tower. The flat was well furnished with all the furniture, dishware, utensils, and cleaning items you would need. It also had a nice selection of books on Florence.
We would absolutely stay at Alberto's again!
