Disappointed after reading all the hype.
I love tripadvisor for the fact that in most cases, any hotel rated highly on the site is well deserving of their status. This is the first time I've been a little let down.
My room wasn't "impeccable." There was hair in the shower, and the nightstands were covered in dust. I thought it was some sort of speckle characteristic in the glass until I ran my finger over the top. And I was aware there were rooms with bad views, but this one had to be the worst view I've ever experienced. "Bad view" does not do it justice. Even on the 12th floor, all you see is a broken down building with a few busted windows. You have to get right up to the window and look directly up to see any sky. I'm not normally a claustrophobic person, but maybe once a year something will trigger it, and my room at the hotel did it for me. 
I was in DC to take a certification exam and wanted to spend the day studying, so since my room was making me a little nauseous from feeling enclosed, I took everything down to the bar/coffee area. It was great until at 11:30am the bartender/waitress brought me my check for a $5 coke trying to nicely tell me to leave (Are you done?) - I'm guessing because of lunch service. She didn't even ask me if I wanted to eat lunch, and it's not even like they got slammed. I got room service later that night after having a glass of wine and wanting another glass and a cheese plate to wind down post-exam. It took about 45 minutes for it to come, and at that point I just wanted to go to bed. Signing for $60 worth of room service was kind of gut wrenching. 
I did eat dinner in the restaurant my first night there, and it was amazing. I couldn't have been happier with the service or my food. I was also extremely appreciative they had nice, big umbrellas you could borrow for free since I had to go out when it was pouring down raining. The location is pretty fantastic. I saw someone in a review complain about not being able to find a bottle of water and having to pay a bar $10 for a bottle, but the area is littered with CVS and Starbucks. Just start walking, and you can't miss one. There's also a decent sandwich shop right across the street that has all kinds of yummy snacks and things. You don't get coffee in your room, but they have pretty good coffee in the bar from 6am-10am with an assortment of pastries for free.
In short, I didn't hate the hotel or anything, I was just let down after reading so many glowing reviews. I got a comfortable bed, a hot shower, a good location, and friendly service. So, I guess that's the point, but for a 4-star, highly rated on tripadvisor hotel, I was looking for the icing on the cake and didn't find it.
