The location is in a beautiful, safe neighborhood. Besides some brief construction when we arrived, it was pleasant and quiet. The people upstairs did not stomp and there weren't any barking dogs around. Right outside the door is the top of Rock Creek Park, which was very green and lush.
PROS: The shower and its water pressure was perfect, filtered drinkable sink water, fancy fridge, availability of kitchen space, comfy bed, lots of lamp lighting, great location if you don't have a vehicle to park.
CONS: Bad location if you're renting/driving a car and have to park on the street. No ice maker, so we just filled up glass cups with water and kept them in there for when we wanted to drink cold water. Flat pillows, but they were comfy when folded in half. Toilet paper was single-ply, and not enough bath towels were provided. Those are all small, fixable things though (except the parking).
Overall I would definitely recommend staying here, and we would stay again in the future after those small improvements are made.
