I don't *love* DCA, but I don't hate it, either. Its best feature is probably the fact that it's connected to the Metro system, which makes it really convenient and easy to get to. It's not a huge airport, but there are enough food and shops to be satisfactory. If you're super lazy, or just have a ton of luggage with you, there's a shuttle that will take you to each of the terminals, but again, it's not like it's not walkable. It's not the most modern or aesthetically pleasing airport (e.g., the baggage claim area), but it gets the job done. I've never really had any major issues with checking in or going through security, and the restrooms are always clean enough. And don't forget -- there's the chance that you'll see someone "famous" (an overrated politician) on your flight.
