The appartment is the perfect fit for a couple which is willing to see more than the touristy areas of florence, since it is not situated directly in downtown. (The main attractions are still reachable on foot though.)
Unfortunately we did not get to meet Chiara herself, but the cleaning lady, and she was very nice. She gave us a short information about all the important things which are to know, and was really welcoming. The bed was really comfy and the appartment just had the right size. WIFI worked perfectly, and we've been provided with little things which could have been necessary for breakfast (Croissant, jam, juice, milk,...) as well as restaurant recommendations.
All together I can only recommend to stay in this appartment!!!
