I've been there. It's fine. The people who work there are really nice.
Most of the stuff was in Costco-standard sizes, so I don't know how people really fit it into their apartment. Also, the membership line is kind of long, so if you don't have a card, you might want to order it online and just get your picture taken at the store. Could save 20 mins.
Two transportation tips:
- Parking in the attached garage is super convenient, but also about $4.50.
