We went to DC for a few days with our 3yo. We wanted a place that was close to museums / zoo but also a nice place to hang out during nap time etc. We loved it -- it was a great space to just relax and enjoy the city. Sunny, bright, clean, and fully stocked. It's close to 2 different metro stops and was quiet at night. I used to live in the same neighborhood and it was great to be back!
