Rolando's place was fantastic. For the price we paid for such an excellent location, I had every right to expect a small, cramped apartment, but instead the residence is very generous as spacious. Everything was clean, the kitchen was fully equipped, and there was even a little Christmas tree!
Rolando's son was a real gem at check in, and gave us some excellent recommendations for where to eat (every single one was a winner). The location is pretty unbeatable - you don't feel swamped by the "touristy" side of Florence, but you're easily within walking distance of all major attractions.
The only fault I can make is that the heater in the bedroom was very loud, so I had some trouble sleeping (no problems for my girlfriend, however).
All in all, this place is great value and a fantastic base when travelling in Florence.
