Laura is a great host--responsive, helpful, and reliable.
Her flat is located in a very central location, directly across the street from the Mercato Centrale and a 5 min walk from Santa Maria Novella train station (which was helpful when my friend and I needed to catch a 4:30 AM train to Venice) and 5 min. from the Duomo. Three of us lived in the flat for one month, comfortably. There is only one true bedroom in the front, a loft room (which is quiet and comfortable) and an additional bed under the loft that we turned into a makeshift bedroom with a screen divider and some sheets hanging from the loft for privacy. Flat is on the older side but has a lot of charm. The full kitchen and long dining table were a plus--we cooked a lot at home.
