It's a fantastic location convenient for walking to most sites or two taxi stands a few blocks away. Be sure to visit the newly opened "Stadium of Domitian" on the outside loop of Piazza Navona.
Wear quality "comfort" shoes. Use anti-theft wallets and/or purses. The street peddlers seem aggressive, but they are respectful of a hand motioning "not interested".
Carmen was easy to reach and offered helpful information, particularly how to access Ostia Antica.
Some reviews complained about the noise from adjoining restaurants at night, but I'll gladly use a pair of earplugs and be in a hip & safe area in Rome.
