Spent 10% of my trip to the nation's capital waiting for an elevator at the Renaissance
Admittedly the Renaissance is undergoing remodeling, but only one out of the six elevators was out of commission when I stayed there in mid-October. Given the size of this hotel and the fact that conventions are frequently hosted there, even six working elevators would be insufficient for the crowds. People were literally queued up on the lobby floor while waiting for the next elevator.
The remodeled guest rooms are spacious and tastefully decorated. I particularly liked the artwork with the presidential theme, including the oversized black and white photo collage in the bathroom. 
At non-peak hours, the service in the Presidents Sports Bar is glacially slow. The adjacent health club, the Vida Fitness Center, is complimentary for hotel guests. It's extremely well-equipped and the locker rooms have terrific amenities. However, nearly a week later I'm disputing a charge for a spa service for which I was double-billed.
