I think this is easily one of the best places to stay in DC. Paulette and Larry make wonderful hosts and ensure that you feel home.
They offered me rides to the downtown area, provided me so many tips and suggestions for places of visit in the DC area. The house is easily accessible to the union station and you've a bunch of stores that are nearby too.
Paulette also checked on me (letting me stay for longer) when my return flight had a possible cancellation because of weather conditions. This was a very kind and thoughtful gesture.
I truly enjoyed my stay :)
