MAD lounges seem fairly hard to decipher. I'm looking for a lounge with a shower upon arrival. EXP arriving into MAD from US on AA metal then transferring to a low cost flight out in the next few days (Spain internal to the islands). What is the best lounge to shower in at MAD? Arriving flight comes into 4S and Departing flight is from 4.
Is Dali lounge in T4 the best option?
