On the plus side, Elena's place is very well located - everything is easy walking distance. She is a responsive and helpful host. An unexpected cold spell had us shivering and she immediately dropped off an extra heater. It made a huge difference. Internet access was great.
A few minor drawbacks - The hot water runs out, so one of us had to bathe in the morning and the other in the evening. (The water takes a long time to heat up again.) The public garbage bins are just across the street and the garbage truck comes by more than once a day starting at about 7/7:30 am. Noisy!
Overall, we would rent here again if our travels take us back to Florence. Thanks Elena!
