Great Location
I stayed at this hotel in June 2012 as it was the hotel of choice for a conference I was attending. Looking at prices, it is good value compare to other hotels in the area. 
With one day off to explore DC, I found the location of this hotel ideal by foot, taxi cab and the subway which was very close to the hotel. The white house is only a couple of blocks away and the national mall is a nice walk away. Starbucks is situated in the hotel along with an ATM machine (that works!).
I personally loved the antique feel of this hotel. Beds & pillows very comfortable and bathroom amenities were great. Room was spacious enough for myself and 4 big bags.
With exception of one man at reception on the morning of June 9th, I found all other reception staff to be straight faced and abrupt. The woman at concierge was incredibly knowledgeable and provided clear instructions and maps on my desired locations. She was truly fantastic!
Restaurant: Ate breakfast and dinner for 6 nights. Maitre d' was always efficient however not much could be said for the table service on any of those days. Food was delicious, good selection and good value which is why I kept going back.
There is no free wifi at the hotel which was disappointing given the other 3 hotels I'd stayed in on this trip through the USA all had complimentary Wifi.
Special thanks to: The housekeeping lady on the 7th floor was a wonderfully friendly lady, Cori at the bar and the lady at concierge all should be commended by management for their outstanding service.
I would certainly stay here again simply because of the above named staff, value for money and location.
