Pros:
Location, 5 min to the DC metro which can get you virtually anywhere. Plenty of restaurants/fastfood choices as well.
Hassle-Free check-in and check-out.
Responsive and helpful host.
Clean bathrooms and good hot water supply.
Quick WiFi connection.
Cons:
Next to nonexistent sound proofing. We could hear ambulances' sirens or people walking by, but that's generally not very disturbing.
No bed sheets. Seems like we're sleeping directly on the mattress and nothing else in between.
Overall still a good value for money!
