This is a very well located apartment - very convenient for all the major sites in the city as most are within easy walking distance. The apartment is really comfortable and very quiet. It is at the top of the building so some people may be put off by all the stairs with heavy luggage but we managed fine.
The supermarket around the corner is ideal and there are some nice resturants in the area of Sante Croce. Try Le Vespe cafe for brunch and Boccadama on Piazza Sante Croce for dinner.
We arrived very late in the evening but Pierluigi was there to greet us and also arranged a taxi for us to return to the airport - very kind hosts. Would defiantly recommend Antonella's place to anyone wanting a nice place to stay in Florence
