We really enjoyed our stay in Florence. Bernardo and Martina are lovely, welcoming and helpful hosts. The check in was very easy, the apartment was very clean. The bed was comfortable, and there was plenty of space to relax in. We were greeted with a local Chianti wine which was very tasty and a nice gesture. The reasons why we didn't feel like we could give 5 stars were: the advertised city-skyline view didn't exist (the apartment looks directly at another residential building), the folding shower door kept opening while using the shower and the street in front of the apartment is incredibly loud and busy at night. It made sleeping quite hard. Everything else was as advertised.
Overall we would still really recommend this apartment as its hosts are wonderful, there are lots of restuarants nearby and it's good value for money.
