We had a wonderful stay at Mauro's place - the apartment is beautifully decorated and very clean, and Mauro was a wonderful host. When we checked-in, Mauro provided us with lots of useful information on what to do and see and circled everything on a map for us which was very helpful! He also had a folder with recommendations on things to do and places to eat/drink which was great.
Location-wise, it takes about 20 minutes to walk to most of the main tourist attractions in town. Mauro kindly showed us the best scenic route for walking into the centre of Florence which meant it was a nice walk, and one you would feel safe doing later at night.
Overall, we would definitely recommend Mauro's apartment to anyone staying in Florence!
