Great find !
Positives: Working distance from metro, abt 30mins (of cos subject to traffic/train frequency) away from Reagen Airport by subway. Within 30mins by subway to downtown Washington as well. Great location
Room is comfortable and clean with basic amenities, and access to kitchen.
Host was there to meet and greet during check-in. Host is also flexible and allow for luggage drop off of u arrivep before check-in time.
Negatives:
May be a little noisy at night (due to property materials), if your flatmates are walking around in the house. Earplugs provided but i didnt use, a I am not so light a sleep.
Personally I did not find the location super safe for after hours/sunset as a lone Asian female traveller ( I think there was a deadly shooting incident during 4 nights' stay.) Of cos this may be due to personal gut feel, expectations and experience.
