This is a great location - it is close to Georgetown's M street, both Georgetown and GW campuses, Kennedy Center, Dupont Circle and all of the places you want to visit while in DC. Please be aware that when they say it is "historic," it means that the building itself is old and, therefore, may present problems similar to an old house - low ceilings, inefficient windows in heat and cold, and sounds/smells from the businesses next door. Also, the kitchen is on the smaller side and doesn't have a microwave (although in G'town, why would you want to cook with all these amazing restaurants at your feet!!!). The bedrooms were a decent size for a historic building but be aware that the living space and bedrooms are on a different floor from the kitchen and eating table.
Just wish it wasn't a pandemic going on while we were here so we could enjoy everything nearby.
