I stayed at the lounge in International Terminal 3. It's a big lounge with decent views of the airport.
Overall I'm not overly thrilled with the experience. The seating wasn't amazing, the flat screens were small. The food was decent but there was defiantly a lack of variety. No complaints about the coffee station or the open bar and the staff was really good.
They made me take a survey as I was leaving to board and promised to make improvements. I will return to see what's changed but for now, compared to the Air France / KLM lounge right across, there's a long way to go.
PS: they have a shower here which is kind of cool.
