I live in SW, but don’t know much about the apartment buildings. Crime is sporadic, but I don’t think random crimes are any worse than other transitioning residential areas in the City. That said, I wouldn’t live on P. If it were me, I’d try to stay north of O and west of 3rd (more activity, busier streets). If I were looking, I’d keep an eye out for rentals from condo owners on craigslist, as well. We’ve lived in SW for almost 9 months – we moved down from Penn Quarter. We miss the convenience of living in the middle of everything, but we’re enjoying SW.
