I lived in a professional women's dorm when I was on a short-term gig in 2007 in a HCOL metropolis. It was great! Close to a public transportation hub, safe, clean, and convenient. I spent the first part of that contract renting a room from a friend in the same neighborhood for $700/mo. The dorm was $800/mo, and I got a private room (shared bathrooms) plus breakfast and dinner included in the dining hall. If you put in an order, they would even wrap your dinner for you and put it in the fridge for you to pick up at your leisure that night and throw in the microwave.
I was the seediest of the bunch... going to work in a t-shirt, jeans, and sneakers. The rest of the ladies wore suits.
