Sandra and her husband are very nice hosts! Room and bathroom are tidy and spacious (room)! In case of cold nights you can ask for extra blanket. Zone is not in historical center but rather calm residential area. It took max 20 mins to get to center on my feet (I like to walk so it's not a problem). Also it takes 15-20 mins of walk to get to Santa Maria Novella railway station. Also, there is another small railway station close to the building, called Firenze Statuto. Next to the building there is a small market with fresh fruits and vegetables and some shops were products can be bought (and with normal prices). I would say this room is the good option in its range and I advice it to book if you plan a trip to Florence.
Also a compliment to cute cat, which always tried to play with my laces :)
