We stayed at Irene and Alains place and had the best time. We never got to meet Irene, but Alain is a wealth of knowledge and extremely helpful(he went out of his way for us). The apartment is on the back of the duomo and 5 min walk to the train station (10 mins with luggage). It is close to everything, I would come back to stay again when in florence. Thankyou Alsin for everything.
