As a salsa (music) lover I tend to visit Latin clubs in most places I visit. Madrid wasn’t an exception. Visited El Son a Monday night. Everything starts late, if you get there at midnight might be disappointed with the small crowd you may find. As time pass crowd keeps getting bigger, and the floor gets full of dancers. Mostly beginner to medium level dancers, and in a corner the pros. Crowd is friendly, place is welcoming. There’s a cover charge to get in but it includes a drink. Nice selection of hard liquors, specially rums. Options from Puerto Rico, Dominican Republic and Cuba among the rum selection. Variety of Latin music including salsa, bachata and merengue. Some reggueaton played as the sunrise approaches.
