Massimo's place is centrally located right next door to the Mercato Centrale - wonderful! My daughter loved the loft with the spiral staircase. The apartment is adorable.
While we visited Italy, the weather was very hot & humid, and A/C in Europe doesn't seem to work quite as well as it does in the US. Fortunately Massimo had a fan (the only one we encountered in our two week stay in Italy), and the evenings were delightful. We were surprised, however, at the quantity of mosquitos in Florence at night - so beware of leaving the windows open rather than using the A/C. My daughter ended up with about 50 mosquito bites overnight. Live & learn!
