Federico is our favorite kind of host: helpful, responsive, and knowledgeable. Checking in was a breeze, and he helped us get our luggage up the many flights of stairs to the flat. He gave us maps of the city along with some recommendations, which we tried and loved.
The flat has great views and everything we needed for 2 people. The location is amazing: 1 block from Duomo, walkable to Uffizi and the train station, and within a few blocks of a few marquee gelato shops. We didn't use the kitchen but did end up using the washing machine, which was great.
