I would highly recommend staying at Pietro's place. It's perfect in so many ways! It's just a quick walk from the train station (we were there in 5 minutes, toting our rolling luggage was no problem). It's a nice walk into the heart of Florence (I think around 15-20
minutes). His place is clean, and there are towels, comfortable beds, an appliance in the room to boil water to make tea or coffee, cups left on the table for us along with tea and sweeteners, some candies left on the beds... just thoughtful touches. Pietro is quick to respond to questions, was there to meet us, recommended places to go, things to do, and helped us with getting a taxi when we wanted a lift to the airport. His place was quiet, convenient, and just perfect for the stay. Out of the three Airbnb's we stayed at on this trip (and our first trip using this service), Pietro's was the best by far.
