We loved our stay. The location was amazing (we walked to the National Mall and dinner in top notch restaurants several times), and we were able to park our car right outside (with the provided parking pass-- that saved us a lot of money vs. taking the train from NYC).
The beds were incredibly comfortable (firm and no backaches!), and we were able to make breakfast in the fully stocked kitchen every morning.
This is a great place for a family.
The hosts were extremely responsive and accommodating.
