The location of Guido's apartment is amazing as it's only a few minutes' walk to most of the sights. The apartment is clean and comfortable and has everything you need. There are lots of stairs to climb to reach it, which didn't bother us, but bear it in mind if you have lots of luggage! We never met Guido but he texted regularly to check everything was ok. On one occasion we lost all electricity in the apartment but Guido responded very quickly to my text and it was rectified quickly. We found the street to be quite noisy at night (I don't know if that's typical of most nights). I'm quite a light sleeper anyway so I noticed it a lot more. Overall we had a great 4 days in Florence and wouldn't hesitate to recommend this apartment.
