We had an excellent time in Florence. Paolo's place could not be in a better location. All the places of interest and the railway station are within walking distance and we did not have to use any transport.
The flat is small but very functional and adequate. The bed upstairs is really large and comfortable. There was some noise at night from the street but was not persistent.
Paolo was very helpful and punctual during our check in. He texted every day to make sure we were ok.
All in all, I would have no hesitation in using this flat again, if I visit Florence again.
