We absolutely loved staying at Alessandra's place. Her apartment is in a great location (most cheaper restaurants which are also popular among Italians are there, but it's not far from the historical centre at all), has an amazing terrace, is close to the supermarket, is overall lovely and nicely designed... We could go on and on about how great her place is, but you have to experience it yourself. Don't be foolish to pick an apartment in the centre in Florence - San Frediano and Alessandra's place is where its at!!
