We really enjoyed our stay at Gaia's apartment...She coordinated with us so we could drop our bags early and talk to her about the area. We loved being in the SMN square...cool area and super close to the train station. The apartment was larger than some of the others we stayed in during our Italy/Switzerland trip! As others mentioned, it is up four flights our stairs which can be tough depending on how much luggage you have. We would definitely recommend Gaia's place for anyone staying in Florence :)
