We had a fantastic experience at the Medieval Apartment. It is perfectly located in that it is within walking distance to all major sites, but also does not feel touristy as it is in a nice neighborhood.

Luca went out of his way to be helpful (arranging airport rides, making dinner reservations/recommendations) and was super responsive to all of our questions both before and during the trip. It was the best airbnb experience I have ever had and I cannot recommend him or the Medieval apartment enough.
