Marco was a great host. He was waiting promptly at the apartment upon arrival and gave a thorough tour of the apartment. There is a living room, extra living room, bedroom, kitchen, and bathroom.
His home is located 5 minutes from the Roma Termini, so we just walked there with our bags. We walked to most sights, but those that needed transportation, we took the bus. There are ample bus stops near the home as well as the bus terminal at Roma Termini.
