The appartment was perfect for our needs, being just 3 minutes walk away from the Catholic university, LUMSA, in Piazza Vaschetta where we were working. The area is in one of the older parts of Rome, near the Vatican, within walking distance of shops and the Ottaviana metro stop. There is a Carrefour about 5 minutes walk away, a minimarket just down the Via Del Falco, and dozens of restaurants in the area. Gianluca was an excellent host. When something went wrong with the hot water supply he was down there and fixed the problem very quickly.
Although the house rules mention the advisability of closing all windows when leaving the flat, I doubt if security is a big problem: the local headquarters of the Municipal Police is just opposite the entrance to the building.
A taxi rank is 3 minutes' walk away in the Piazza Risorgimento, and from there it takes just under the hour to get to Fiumicino Airport.
