Sarah was very easy to communicate with from the start. She let us drop our bags off at the place before the official check-in time and got us quickly oriented. She also provided snacks and a bottle of Prosecco in the fridge, which was really nice. The place itself is in a quieter, residential area on the other side of the Arno river, which is a nice break from all the crowded, touristy areas.
You can still walk to the Ponte Vecchio and train station (Firenze SMN) in 10 minutes, so it's still centrally located. The place itself has 5 bedrooms and 2 bathrooms, which was really nice for my family to each get their own bed. The apartment has less natural light in the common spaces, but in the scorching heat of Florence summer, we welcomed the cool shade of our apartment. Overall, an enjoyable stay and I would recommend this place for large groups!
