Sylvia's place is a must stay when you're visiting D.C. The location is close to the capital in terms of Uber, roughly a $5-$15/ride (depending on pool or solo). The sizes of the bedroom and living room are large and beautifully decorated.
The only thing better than the room and the amenities is Sylvia. She makes sure that you're well-taken cared of throughout your stay.
Will definitely stay again next time in D.C.
