Mi Experience at Roberta's apartment was perfect. Roberta is a great host. She took care of every single detail. For example, the airline loss my luggage for 4 days and Roberta help me out with it, trying to search more information about the location and contacting with the firenze airport.
As for the apartment, not too much to say. It's simple the best. Perfect location, big spaces and very well decorated.
I would highly recommend Roberta's apartment!! It looks better than in the pictures!!
