A useful independent-access option in the satellite terminal, though it is less compelling than the airline lounges for eligible premium passengers.
Neptuno is Aena's airside lounge in the T4 satellite, with showers, Wi-Fi, work areas and food and drink. It is the Priority Pass-listed lounge for T4S.
Use it if you have an eligible pass and are already in the satellite; returning between T4 and T4S is impractical. Like the other Aena lounges, it can be busy around long-haul flight banks.
