AEP is the other airport in Buenos Aires aka the Aeroparque Jorge Newberry. My flight to Iguazu left from there this morning and I arrived to an even hotter location. The newest hotel is actually a hostel but I have a private room. The hostel itself is more like a resort with a nice pool, large open area with a bar and restaurant etc. and some outside areas I have yet to explore. The only down side is the air conditioner that sounds like a jet engine.
