Just click the "reserve" button. You won't regret it. This is the type of place that even if you live in DC, you should book the room as a "retreat/recharge" from your daily life.
Arriving in warm weather, you are greeted by a beautiful array of flowers in the front garden. The place is calm, quiet, and the room spacious. When I walked through the Hingham door, I thought I could stay in this room for the next two days (leaving for meals) and be completely happy and content. But alas, I had planned a very busy and full schedule, so the room and house became a nighttime sanctuary.
Its location is a quick walk from the U/Cardoza metro station. Pulling a wheeled carry-on sized luggage between station and house was easy. Many eateries within a few block walking distance. I chose this place because of its walkability to 9:30 Club, which was ten minutes on foot.
Touring the downtown/National Geographic Museum/Natural History Museum - all were accessible by a single (no transfer) bus that runs within 1 - 3 blocks of the house.
The little touches that matter: 1) the water bottles in the room as it was summer weather and having instant access to water allowed one to stay hydrated, 2) collapsible umbrella in the room's armoire, 3) blanket in armoire - if AC felt chilly, and 4) air-exchanger units in the room and entry-way.
It was a real treat to stay at this Airbnb.
