If you are in Florence go to the Ancient Arch you will not be disappointed. The very kind Matteo will be able to advise you in the best possible way, I say this because he helped me book 2 last minute tickets for the Uffizi and advised me to go to Enzo and Piero's trattoria, we ate so well that I decided to come back as soon as I can. Last but not least its location is excellent 5 min from the station Santa Maria Novella.
