Location great, room not so great
We traveled to DC over Columbus Day weekend for a wedding. We LOVED the location of the hotel - close to the Metro, Starbucks, eateries, etc. We also liked the decor of the hotel - very modern and sleek. The final thing we really liked was the bed - very comfy. 
However, everything else about the room itself just sucked. I've had a better night's sleep in a group hostel room in Amsterdam than this "4-star" hotel. 
The bathroom - this was set up to look cool but was totally dysfunctional. First, there was no door between the bathroom and the bedroom. There was a small door between the toilet and the sink but it only provided visual privacy, no sound privacy. It was really uncomfortable to use the toilet. I love my husband but there are just some things I don't want to hear. There was no shower curtain, only a super sleek looking, super useless half-wall up near the shower head. As a result, shower water sprayed out all over the bathroom - kinda dangerous, definitely annoying. We called the desk and asked about a shower curtain, they said they had to check and get back to us. No one called. We stopped by the desk and they said they might be ordering shower curtains (?). We asked for a bunch of extra towels to put on the floor.
The room - there was no dead bolt on the door. This, combined with the wacky do not disturb sign (see below) resulted in me opening my eyes at 8 am and finding a member of the cleaning staff standing just inside our door, presumably trying to figure out if she should clean our room. So there were definite safety and privacy concerns. This combined with the fact that the metal room door seemed to super-conduct hallway noise (other guests' doors, elevator, voices), I got very little sleep. Finally, the do not disturb sign was a metal button that you pushed on the inside of the room, which lit up a red electric "do not disturb" message next to the door in the hallway. Very cool concept, but poorly thought out. The only way you could tell if the light was on was to go outside and look. I think the morning the mad came in, we had neglected to go out and check if it was on. All in all, if location is your main priority, I could recommend the hotel, but otherwise I think a traveler could have a better experience elsewhere.
