In all my visits to Florence over the years, I can say that Gaia's flat was the best one I've stayed in so far. The location cannot be beat. It is within walking distance of the major duomo, Mercato Centrale, and everything of interest in the city. The flat is also quite close to the SMN train station, in case you are arriving by train or shuttle bus from the airport. The flat is very well organized and clean and even comes with an incredible rooftop that we would've enjoyed far more frequently had it not been for the slightly chillier nights (the elevator is a true bonus for those of us with a bit of luggage). Gaia was an amazing host. She was very responsive and made both the check in and check out process incredibly easy. I am positive I will be a repeat guest on any future trips to this great city.
