We got lucky, this place came up under a hotel search, and for a similar price to a hotel room but, it was a luxury 2 bedroom apartment. 5 star all the way, room was prepped when we arrived with everything you'd need for a short apartment stay, staff was very professional, and location if you are not familiar with Chevy Chase MD was very nice with dining, food, etc. within walking distance. My guess is these are corporate rentals and occasionally pop up in the event of a cancellation. So, if you can get it, take it. Only thing to be aware of is you'll have to get a little creative with parking if you don't want to pay extra.
