Best bets: 1-In front of elementary school on S St just east of 13th 2-Riggs 3-13th St 4-Vermont Ave just south of S St (Honestly, I've never had to try Vermont Ave because I've found parking at one of the other three or even right on 14th street. 6:30 is a good time to arrive because the "2-hour limit until 8:30" spots just become available.) Plenty more streets across 14th suppressed have open parking in weekends.
You'll have to find street parking in the neighborhood. The area is always crowded so I would arrive early to look for parking.
