Jewel of a Hotel

Liked: The room size was good. The bed was extremely comfortable. The lobby was refreshing and inviting with great aromatic fragrance.
Disliked: The bathroom had a shower. I really wished it had a tub.

Superb

Hotel staff and restaurant staff...

Liked: Room was very clean; bed was very comfortable; except for the emergency vehicles on the street, the room was quiet.
Disliked: The room would have been much more comfortable w/ a few comfy chairs and a "coffee" table. We used the couch for our suitcases because there weren't any suitcase racks in the room. Having to sit on the bed while watching TV or reading wasn't the most comfortable.

Liked: Staff was excellent. I left my cell phone at check-in & the agent brought it up to my room 2 minutes later. Can't beat that for service. Location was great, upscale area, convenient to Dupont circle metro a few blocks away. Outdoor dining nearby.

Passable

Liked: The location of the hotel is hard to beat, very central, easy to get to a lot of thriving neighborhoods of DC.
Disliked: The room I was in was incredibly noisy. A lot of unexpected banging throughout the night and early morning, likely due to being adjacent to the service elevator. I did not get a good night's sleep on any of the nights I was there.

Very nice hotel for a...

Liked: Everyone was so friendly and helpful!
Disliked: Wish they had vending machines for late night snacks.

Very good

3 night stay in Adams...

Liked: Great location between Adams Morgan and Dupont Circle. Easy to walk anywhere in either of those neighborhoods. Bus comes right down Connecticut Ave past hotel to take you downtown. Metro at Dupont maybe 0.5miles away at most. 9th floor very quiet. Décor was much nicer than depicted on websites. Comfortable beds and pillows. Good bathroom setup. Free bottled water. Staff pleasant and helpful. Free coffee (which was quite good) and flavored water in lobby. We went to several excellent restaurants, usually on foot or by ride service.
Disliked: Parking is expensive ($60/night) and is strictly valet. You don't know where they park your car and they have the keys so you need to call anytime you want to take the car out or retrieve something from the car. However the valets were always available and were quick to take/retrieve the car. There is no available street parking without a sticker and I did not see any convenient public pay lots.
