The apartment was in a great location! Everything we wanted to see in Florence was within walking distance. Francesco was nice enough to let us check in early. The only issue we had was that the further we were from the apartment's door, the poorer the WiFi connection was (It seemed that the modem might have been in the apartment across the hall). However, that in no way affected our trip.
I would highly recommend this apartment as it is super close to the sights and very affordable.
