My partner and I spent 3 nights at Alberto's place. It truly has a stunning view of the Arno and Ponte Vecchio.
It's an easy walk from the train station.
The numbering of the buildings on Via Bardi is a bit confusing, but once you know the apartment block is between the two frontages of a wine shop it's easy to find! Kampala met us and showed us in and gave us a quick overview of places to visit.
We spent two evenings sitting with the windows thrown open drinking wine and eating Italian cheeses and meats from the well-stocked supermarket opposite the front door.
The location is superb, with all the sights of the city right on the doorstep.
We particularly enjoyed wandering in the Altrano area and found a wonderful local restaurant to eat at with a gelateria opposite which did cones of delicious ice cream for a euro.
Also, don't miss the upstairs of the Mercato Central for a fabulous choice of food and drink all freshly made from the market.
We'd happily return and stay here again if we have the chance.
