Just a quick update on the lounges situation... The Lisboa and TAP Premium lounges are closed as of today June 1st, 2015. Renovations going on it seems.
They direct you to the ANA lounge (not NH, it's a company called ANA...) right in the middle section of the airport, between T1 and T2, upstairs. You can't miss it. The only escalator that leads up is going to this lounge.
Wifi access, magazines, newspapers, etc... some food, Nespresso Pro coffee machine, juices, tea and shower (it says a Spa is coming soon).
