Moderately priced, centrally located
The Hilton Garden Inn's proximity to Verizon Center in Chinatown was the main reason we picked this hotel for our overnight stay when we were in DC to attend the Coldplay concert earlier this month. The rooms are really spacious and have a microwave as part of the amenities, a big plus! There's also a Whole Foods just downstairs. This was a big boon when we returned after the concert at 11pm to find all the restaurants shut. The bathroom, though not luxurious, was definitely very functional and I loved that they have Bath & Body Works toiletries :)
It took us 5 mins by cab to Union Station from where we boarded the Amtrak to NYC. (The Noma metro stop is right behind). I'd recommend this hotel to all business travelers and people who are looking to be close to a metro station.
