Amy's basement apartment is a great choice for your trip to DC. She has parking (we have not used it but which is not usual in DC ), the bed was comfortable, you're within walking distance to lots of shops and restaurants, and there is plenty of space.
She does not joke around about the noise level of the kids in the morning. We didn’t mind so much, but it was quite noisy.
If you're looking for a great location to spend a night or two in town I highly recommend checking this place out
