This is the place to look out for if you want to base yourself in dc especially Dupont circle. For me it worked out really well as bigbus tour bus stop and MTA commuter bus stop were just nearby. Lots of restaurants and cafe nearby and not a noisy neighborhood at all.
Cuban room had a great feel to it and checkin instructions were clear cut. Nicole was available for any questions or help whatsoever. Bathroom can get a bit cold though as there is no central heating in Cuban room and its done via wall unit.
I had a great stay at Nicole's place and would highly recommend it to others :)
