I generally give good feedback and keep it simple, but I’ve found detailed reviews helpful when choosing where to stay and can also encourage the host to make improvements, so:
Pros:
—The location is pretty awesome, particularly if you are there to visit AU. There are many restaurants located on the same street, Starbucks across the street, and a large grocery store at the end of the block.
—Having access to a washer / dryer particularly at the end of a long trip was very nice.
—The host kindly allowed a later check out (we left at noon) so we could store our bags while doing the American University tour.
—Having a separate “office” little space was nice to work in (though the internet was slow).
Cons:
—The small 2nd bedroom has issues: poor twin mattress, the back door has windows but no blinds (bright at night), host requests to keep the backdoor outside light (a bright light!) on, there are three big potted plants in that bedroom window which are not easy to move to use the blackout shades on the window behind them (but with the backdoor window, I’m not sure how much it helped anyway), and there are thin walls (on our last night the neighbor’s music was disruptive to sleeping).
—Host made a request at checkout to strip the bed sheets and wash them along with the towels. I’m used to taking out the trash, putting towels in the bathroom, cleaning up after ourselves, but starting the additional cleaning when charging a $150 cleaning fee was not an acceptable request — nor was that in the fine print of expectations when I booked.
Bugs: Bring mosquito repellent if you want to enjoy the little patio. Tons of mosquitos and bugs. And there were many plant “fruit flies” that seem to come from the interior plants, which then navigate to your food (different bugs than the gnats which populate right outside the front door).
Upon arrival, there was a snicker bar trash paper on the couch (not a great first impression). The used sink sponge smelled of bacteria, so clearly was not new & needed replacing. (Maybe time for new housekeeping at $150?)
Cost: after adding the cleaning fee and Airbnb fees, it was just shy of $500/night - expensive even for the DC area.

Overall a good experience though over-priced for what you get.
