Just fine, but not for everyone
Stayed here 2 nights for business, a first-time visitor to this hotel but not to DC. Took the Metro from Union Station, and the proximity to the Foggy Bottom stop was a plus. The surrounding University environment felt safe to walk in at night. 
At check-in the desk staff was very helpful, they had several restaurant recommendations and menus, including the Notti Bianche across the street which was pretty good. $3 small plates at happy hour. Did not take them up on the cookie, but they had fruit and bottled water. 
The queen bed was SERIOUSLY comfortable, the best part of the room. Slept great on it (although the quality of hotel pillows seems to be declining everywhere). Also my room faced away from the street so it was extremely quiet (except the refrigerator - more on that later). The room was clean. Didn't watch TV in the bedroom, but it was fine in the living area. The climate control was good. Large work/dining table was great for the laptop and assorted other stuff - way superior to the average hotel room desk setup. Wi-Fi was okay, not slow but not fast. If you are a HHonors member they waive the daily Wi-Fi fee. 
The photos on the Web site do the room justice pretty well. Plenty of space - it seemed a shame to have it all to myself. As with any older property, particularly one not originally built as a hotel, there are some quirks. My bathroom was almost laughably small. Minimum space on the vanity. And there were no outlets around the vanity, they were on the wall behind you by the light switch, which made for some interesting hair dryer and curling iron logistics. But the shower pressure was good and the towels were substantial and soft. The closet was fine. That's where they hang the hair dryer, if you're looking for it. 
Kitchen was handy, though didn't have much chance to use it. The room service breakfast offerings, pricing, and possible wait time didn't appeal to me, so I picked up some cereal and milk at the Whole Foods. The first morning there were no bowls in the cabinet so I ate my cereal from one of the (sizable) paper coffee cups. The next morning I noticed bowls had appeared. As another reviewer commented, my refrigerator was VERY noisy so it was a good thing the bedroom had a door. 
The Whole Foods is not to be missed. It's the first time I've visited one that had two stories with escalators, and five lanes feeding traffic to the checkout registers using display screens overhead. 
At check-out time, the elevator seemed to stop at almost every floor - which I was concerned about in advance, but not enough to horse my bags down 8 floors worth of stairs - and the very small lobby was crowded and noisy. Fortunately the waiting area outside is covered by a large awning and the doorman was courteous. I was curious about the rooftop pool but didn't go up to look. 
Someone expecting a basic Hampton/Fairfield may be put off by this hotel's setup and the fees for parking, Wi-Fi, breakfast etc. It worked just fine for our purposes, and the pricing was much better than surrounding hotels for those nights.
