We really enjoyed our stay!! The apartment is cozy and beautiful. Location is perfect (5m walk to the Duomo, 10-15min walk to Ponte Vecchio...). You can actually see the dome through the window!!
It's well prepared for warm and cold weather, and it was very clean.
If you don't mind climbing some stairs is a really good choice for visiting Firenze.
We didn't meet Enrico, but he sent a friend to welcome us and she was very nice. Communication was easy with Enrico, he even recommended some places to eat :)
