My friend and I had a wonderful stay in Firenze at Annalisa and Leonardo's. The place is ideally located, just minutes from San Marco and Brunelleschi's Duomo, both incredible must see attractions in the city. Uffizi museum is a very short walk.
The apartment is a wonderful blend of old time charm mixed in with modern, comfortable renovations. There is a great Air-conditioning system al throughout the apartment, so staying in the summer is very doable. Taking a relaxing bath after a long day of walking through the city is very rewarding. I will definitely stay again!
