I came to DC for my birthday and had a BLAST! I loved the location - it was far enough from the hustle and bustle of traffic, but close enough to everything you’d want to do.
Andrew had a bottle of wine, cupcakes, and chocolate upon arrival which I LOVED. My only con was the lock didn’t work when we arrived back one night. It was extremely cold, but eventually we were able to get in.
I recommend this location if you’re in the DC area with a friend or two
