I stayed at Luca's very well appointed apartment for almost 2 months and everything was perfect. Place couldn't be at a better location; it's outside of tourist area but at the same time just a few minutes away by foot from everything(LinguaViva school, Central Market, Duomo, great restaurants,supermarket, etc) which means you will not get the noise from pretty much everywhere else in the city. Apt is really quiet, especially at night. You will not hear a peep. The same cannot be said about other apartments,as Florence is a very busy city.
It has a great living room, big closet, very nice bathroom and kitchen. Bed is very comfortable! Luca and his sister are beyond nice! They are very accommodating and I could not have asked for better hosts. No need to research any further. You will not find a better place !
