Horrible beds, poorly thought out rooms
I chose this hotel because it was convenient to where I had business in Washington. I regret it.
Where to start. The lumpy bed is the worst I have seen in many years of business and leisure travel. The bed sheets are of low quality as well.
The rooms have a very dated shabby feel. Ugly yellow and brown swirl carpeting. Ugly upholstered arm chair that looks it was rescued from the 1950's, crammed into the corner of the room. The ugly yellow curtains also look rescued from the 1940's or 1950's. 
The bedside lamp is extremely bright with no dimmer -- too bright when you are trying to wind down and read before bed. If you want a dimmer light you have to walk across the room to turn on the desk lamp, which means you will either have to sleep with the light on or just when you are ready to fall asleep get up and switch it off.
Bathroom very small with no separate shower.
The hallways look very shabby with ugly red carpeting. (to say this hotel is not for the design conscious is an understatement).
The only positive things I can say is that the room seems clean, there is a convenient charging station at the desk for charging electronics and the security guards and bell hops are very nice. Oh, and I like The Republic of Tea ice tea available in the minibar.
Also be aware that the Pennsylvania Avenue view rooms are very noisy with a lot of street noise. I downgraded to a no view room which is much quieter. In the first room, I also heard a lot of noise from adjacent rooms.
For someone used to staying in hotels like the Sofitel, this place does not cut it. I wasn't expecting the Four Seasons, but I was expecting a decent bed.
Under no circumstances would I stay at this hotel again. Next time I'll stay at a decent hotel and just take cabs to my meetings.
