Location is 200 m from Roma Termini and just outside the building you can get cabs and bus to airport. Good places to eat nearby. Shane made the check-in process very simple and was very helpful and accommodating. There is a common kitchen where lot of food items are stored and its free to use.
Being very close to termini and road, expect some noise from outside during night when mainly people return from party but that's fine to adjust if you want that kind of location.
Shane is always available to resolve your query to make things easier for you.
Highly recommended.
