Booked three nights at the Relais Dei Fiori and were pleasantly surprised. Only ten minutes from the airport and eight euros in a taxi or two euros by bus. The hotel itself is lovely and clean with recently refurbished rooms. The staff were so helpful, especially Marvin who worked in the bar area, he really looked after us with lots of gorgeous little snacks while we had a few drinks.
Breakfast was okay but nothing to get too excited over, lots of bread, cheese and ham!
The location of the hotel is really central, just around the corner from the tower and the other monuments. Once you've seen them, there isn't an awful lot else to do other than sit in lovely little bars, drink wine and watch the world go by. We did plan to go to Florence for the day but felt there was just enough to do for three days and we really did have a fantastic time.
One word of warning, check prices of drinks before ordering, we were charged 77 euros for two beers and a bottle of wine at one bar which was definitely overpriced.
Other than that, great hotel and great break.
