The Air France lounge in RUN is very very small (of course, only one flight a day...) If there's a lot of passengers on AF 679, the lounge is very crowded, if the flight is empty, of course, the lounge is quiet!
one shower i think, toilets, coffe maker, drinks and a few snacks...and internet, when working!... I don't spend many hours in lounge in RUN because I go to the airport just at time to board.
In july I was on MRU-CDG flight, very beautiful lounge in MRU, especially the First lounge downstairs (and very tasty Pommerol...), business lounge is located upstairs (and "just" Pauillac to drink.....
)
