Perfect location (in the middle of everything, yet a block removed from the crowds); great apartment - beautiful and everything worked well; and very professional service. Ilaria met us at the apartment, provided all necessary info about the apartment, surrounding area, supermarket, restaurants, etc.
One thing that people should realize though is that it is very hard to reach the apartment in your own car (a taxi can take you there) and Ilaria does not recommend driving to the apartment. If you arrive in Florence with a car you would have to park it somewhere and it is not going to be right next to the apartment.
