It goes without saying that the airport is a major convenience for those us that can use it for non-stop flights. There are well "proofed" transportation signs to get out and back into the airport. Of course, be warned that once on the freeways (especially towards Maryland), use updated maps or else getting back on track will require a scenic detour (I got an unsolicited drive along K Street).

Love the architectural details (since I travelled there nearly 20 years after the initial renovations were completed). The facilities are compact and therefore lend to congestion. I didn't realize that there were THREE runways since I have seen only one in use during my limited trips.

Love the River Visual Approach because of all the turns during final.

Do your homework; if you can use Metro during your trip (to avoid parking hassles) you can use it conveniently from the airport.
