In all important cities in the world there´s a nightclub which is situated in a basement where they play the best electronic music in the city. That place in Madrid is called Coppelia 101, a club which will make everyone who is looking for the best local DJs have a great time.
The interesting thing about Coppelia is that if you go in before 2am it´s free to go in (with passes although they´re easy to get) and automatically you will go down to the basement where the party appears by magic. The place is pretty big and dark but there are plenty of lights that accompany the music.
The atmosphere is calm as well as fun and everyone will be in their own world without bothering absolutely no one. The drinks in the different bars are really affordable, therefore drinking a few beers with your friends or your other half won´t be a problem for your pocket.
Also, on some weekends, the club brings foreign DJs and that´s when Coppelia explodes, fills up with people and the nights are longer and better.
If you want to visit one of the most important clubs in the city you can get Madrid accommodation and not let this chance go.
