Supreme's place was very much as advertised. Lots of nice little amenities. A welcoming, gated walkway up to the property makes it very appealing from the outside, and the community was very quiet, which is incredible for the 4th of July in DC.
We saw Supreme a few times during our stay and he is very friendly, and he was responsive to questions for the most part.
A few minor issues that weren't detrimental to our stay: the day of our stay, Supreme let us know the dryer was not functional which was disappointing. The wifi was spotty, and the living (futon)/dining (small table) area were functional but not overly comfortable. I also believe the cleaners missed a few obvious smashed mosquitos on the wall.
As a basement apartment Supreme's space worked well for our stay (myself and my teenage daughter) and we would consider his place again for a brief stay.
