We had a great time in DC. Dan and Chingchai are very nice and caring. They won't bother you if you prefer privacy but if you need anything, they will be there to help. The house is very spacious and full of travel memories of the hosts. You will also have access to the whole first and second floor. The neighborhood is beautiful. There is a big cherry tree blossoming right now in the front yard. We walked to the mall along the 14th street. It's just about one hour and many interesting shops along the way. I would definitely come back again if I visit DC.
