Monday salsa class at Church of the Blessed Sacrament

Church of the Blessed Sacrament is at 157 Copenhagen Street, London N1, in Islington's Caledonian ward, north of King's Cross. King's Cross St Pancras is the nearest tube, about 13 minutes on foot, which also puts it in easy reach of the mainline stations there. Esencia Libre teach here every Monday from 7pm to 10pm. It's a class night rather than a party, with courses at beginner, improver and intermediate level in both On1 and On2, so it's a solid place to start from scratch. The listed price is £10; check Esencia Libre's site for course booking. The same team also teach on Thursdays in Marylebone and run a monthly Sunday social in Somers Town.
