When my initial plans to visit DC with my two children fell through I was extremely unhappy. A web search found Airbnb, which led to Charlotte. I am now extremely pleased that my initial plans failed so my children and I could meet, and stay with, such excellent companions.
Here are some area amenities in no particular order;
The Capital Crescent Trail and the C&O Canal Towpath are an excellent biking experiences. Bike to down Georgetown and go to Georgetown Cupcakes, I'm still aglow from that bit of sin (but not on the weekend, there's a line around the block).
Near by is Listrani's Italian restaurant, well priced with very, very good food.
And, of course, all the rest of the stuff in DC.
So, again, Thank You Charlotte and Co.
PS - D & A are demanding an encore.
