The apartment would be ideal for a single traveler or a couple. We had issues with the heater but Daniele responded and fixed it quickly. The only downside was the shower. Both my friend and I had to take cold showers (hot water only ran for a good 2 mins) the entire time we were there, no matter how long we waited for the tank to fill up. Probably wouldn't be a big issue in the summer. However it is an old apartment in the middle of Florence.
It is in a good location and everything was pretty much in walking distance. Daniele was also very prompt with his responses and gave us some good recommendations with restaurants and bars etc.
