Sala Moon is a big, two-room nightclub a short walk from Joaquín Sorolla AVE station that doubles as a salsa/bachata social venue and a concert space. The layout is straightforward: a large main room with a roomy dance floor plus one or two side rooms that organisers use for simultaneous workshops (reviews mention bachata and kizomba classes held in different rooms).
Doors tend to open late, the Google listing shows regular hours Thu–Sat 23:30–07:00, and the main floor fills after 23:30; expect the busiest stretch around 00:30–02:30. Supersalseros run a regular Sunday social here (check the event page before you go). Cover for socials is typically around EUR 9; bars and staff get consistently positive mentions in reviews. If you prefer space to warm up, aim for the workshop start or arrive early, once the DJ sets in, the club becomes crowded fast.
Price: 0 EUR
