Satellite 1 is a pretty nice space which was refurbished a few years back.
Satellite 2 is a bit shabby and still in the old style that satellite 1 was in before its refurb.
Satellite 3 is like a third world bus station and is what 80% of Stansted’s passengers seem to base their opinion of the airport on. It is in my opinion, truly horrid at the far end gates.
