Nice place, comfortable living room/kitchen area, but location not ideal for 1st time visiting DC for it’s a bit of a drive through traffic to get to national mall area. Also, If you’re taller than 5’ 10” look elsewhere for it’s a basement unit and your head may hit in parts of the ceiling or may have to be ducking the entire time when you stand. Also, you can hear the family upstairs, including the kids from early morning and throughout the day. So if you’re a light sleeper reconsider your options.
The family is easy to communicate with though and they have done their best to make you feel welcomed at their Airbnb. Also, nice that they give you your privacy and don’t bother you unless you reach out to them.
