We stayed in total 2 nights. The apartment we were staying in (just next to his one) is cozy and stylish. The bed was super comfortable, especially when you were the whole day on your feet as we were..
Check in was great (even though we were checking in at 9pm) we kept in touch easily - no problems!
Location was convenient, we recommend to take the bus line no.1 to go to the city centre, wich leaves almost in front of his door - takes about 20min.
All in all we highly recommend the stay if you wanna spend some nice days in Firenze :)
