We would highly recommend staying with Ada and Sergio. The room is extremely cosy and comfortable, plenty of space. Bathroom is spot on, very clean and brand new - shower is hot and consistantly hot! They had left a little welcome tray with teas and biscuits and crackers, it was lovely. They both welcomed us and made sure they'd be here when we left as well to say goodbye. Sergio gave us plenty of tips for our stay on what to see, visit etc. He gave us a map and added notes on it. It was great to have it and we had a wonderful stay in Florence! It's a 30-min walk from the main train station, 15-min walk from the cathedral and historical centre. Pleasant neighbourhood with lovely restaurants.
