Hi, depending on the time of the day, you can find space on small streets around Wisconsin ave - it is free for 2 hours, but usually buzy. There is also a parking lot right across Wisconsin. Check more parking details on our friend's website https://insomniaescaperoomdc.com/parking/
Parking is tough, recommend getting there by public transit. If you park, get there early and prepared to search and walk far.
