I stayed here on business, and my stay was fantastic. The room was extremely clean, not too cold, and not too warm.
During my stay, my toe was broken and the hotel staff helped me with some first aid supplies for free. They were all very kind and none of it felt forced. It never felt fake. Everyone was just genuinely nice.
If I come back to Tysons Corner, you can bet that I'll be back at the Crowne Plaza.
