Great apartment, close to Trastevere train station, the tram and bus, makes getting around to all the sites of Rome very easy. The neighbood is safe, but doesn't look it, if your getting off the train from the airport & walking to the apartment, you have to go through a tunnel under the train station tracks that has some great graffiti art, but a night is very dark. If you've been to Rome before, you'll know what I mean, many safe neighborhoods don't always look or feel that way, but they are, so if you understand Rome, you won't be thrown by the graffiti and dark tunnel, but if you're arriving there by train at night for the first time, you might want to take a taxi the short distance from Trastevere Station.
