Diego and Leonard are the ultimate hosts. I only wish I had time to get to know them. You can reach the apartment via Train from the airport to Termini Station. Then a bus from the train to Allisi bus stop. Just a few blocks and you will find the apartment. The apartment is an artist loft style. You can tell it was built with a lot of creativity and TLC. Small kitchen good size bath plenty of comfy couches and a very comfy bed. We asked Leonard for dinner spots and he pointed us around the corner to a few cute restaurants. From this apartment we hopped cable cars and buses to all the sites. This is a lot less expensive than cabs would be. The location is within the city and I would recommend to all.
