Living there seemed cheap compared to Boston for me, but yeah, and it's only gotten more expensive since I moved there 15 years ago for a job pretty much right out of college. I was able to afford a much nicer apartment there, though. Had a washer and dryer in unit. PS - Just looked it up. Boston is still more expensive than Washington. Boston is the 4th most expensive city in the country. New York is number one. D.C. is #6. So yeah, D.C. should actually seem cheap to her coming from New York, much like it was for me when I was closer to her age.
