Elizabeth's place is the best kind of airbnb. Clean, well-decorated and thoughtfully-appointed, but uncluttered and easy to "live" in. If there was ever anything we needed that we didn't have, it always turned out I just hadn't found it yet! Enough cooking implements (and simple, but appreciated, things like salt and pepper in the cupboard) to make simple meals and extra blankets and other things to make the stay comfortable.
The apartment is a basement apartment, so no great views, but the veranda is lovely and the neighborhood is quiet and green with easy access to park space, a library, Whole Foods, and the Metro as well as restaurants and bookstores in multiple directions. Very convenient to both downtown DC and Bethesda, both by taxi and train.
