The perfect one, closer to everything just 3 minutes walk from Capital One Arena, the restaurant fantastic and the staff awesome, the only thing that I paid for a King room that was supposed to include mini fridge and microwave and neither of them were there, I sent a message to Expedia but still they the fridge and microwave never arrived. Which it means wasting money for nothing as $340 for a night without those things is considered expensive. I will definitely go back even that I was so disappointed.

Location was excellent to many of the Washington DC popular sights. Capitol was in walking distance as well as many of the other popular sights. Hyatt on Capitol Hill has a nice restaurant/bar if you choose to stay in. Hotel is clean and comfortable.
