I cannot emphasize enough what a great location this is. 10-15 minute walking distance to Union Station, or H Street which features restaurants and grocery stores. 30-40 minute walking distance to various spots on the Mall. We were able to walk and use mass transit to 85% of the places we wanted to visit on our trip. Ebenezers Coffeehouse about 2 blocks away has delicious coffee, and Union Kitchen across the street has a nice selection of snacks, drinks and makes a mean breakfast sandwich. The neighbor is very nice and is quiet by city standards.
As a chronically ill and disabled traveler: This location is a little more expensive than nearby hotels (esp once you factor in the cleaning fee) but the kitchen and nearby groceries meant I could cook for myself or buy prepared meals nearby that accommodate my dietary restrictions. Comfy bed and bathtub helped with managing pain from all our walking. The basement level and air conditioning kept the space cool and comfortable. The steps to the door are steep and irregular, and the neighborhood sidewalks are also very uneven.
