We stayed at Serena and Fabio's place for 6 nights and everything went smoothly. The apartment is well equipped and within walking distance of Florence city center. There's also a metro stop less than 100 meters away. The self check-in procees was easily communicated, and Serena and Fabio replied very quickly whenever we needed more information or some help. The apartment was very clean, modern, and spacious. A nice hub to explore Florence from without being in the central tourist zones.
