We enjoyed out stay at Barbara's place! The apartment is cozy, clean and has nice interior (it is a studio with 4 sleeping places).
It is located 5 min walk from train station, so it is very convenient if you arrive to Florence by train.
Hosts were very welcome! we've arrived a little bit earlier than the time we've appointed, but they were able to come check us in very quickly.
I can totally recommend you to stay in this apartment!
