YOu know when I was in Ibiza..I think we were in San Antonio side of Island....make sure U are on other side..There r buses going down main road to all clubs...believe me here u wont have any trouble finding clubs..make sure u go to beaches Too! I cant really remember going to any big clubs in Madrid..I mainly went to bars, but I do remember getting flyers for clubs in the hotels. See if you can find Madrid Rock..its a music store but they have flyers there:)
