My stay was perfect! I was in Florence for 2 weeks and by the end I felt as a resident already. The position is great and there is a bus stop very near that can help, specially at arrival and departure with the heavy bags. Tina and Diego were very helpful from the get go and are ALWAYS there if you need help, not only about the stay.
The apartment was always spotless, kitchen had everything to cook a real meal. It’s truly a great place to live, even if for a couple of days, such that I didn’t mind the steps on the stair (nearly all Florence buildings in the centre will not have lift)
