Hillary's spot is conveniently located for activity in DC or Maryland. All the sights you want to see are within a short distance (which is great because traffic in DC can sometimes be a nightmare). It's also about 20-30 mins from National Harbor depending on traffic.
The decor here was warm, cozy and tasteful, and everything was neat and clean. The bed is also super comfortable (which is important after a long day of doing tourist things lol). Hillary is very responsive and helpful if you have questions or concerns. You probably won't have any questions though because Hillary is thorough about making sure you have all the information you need for your stay prior to your arrival.
I'd definitely recommend this Airbnb for visitors to the DC/Maryland area.
