Used this lounge in June this year, and it is located exactly as you state.
It is a small lounge and thirty people may be pushing the available space. Drink selection was as usual, a selection of beers and spirits, and the food was basic snacks, salted peanuts crisps etc. I was there in the morning and there was a selection of bread, cheeses and meats, I don't know if they were there the entire day.
I thought space in the airport was limited for sitting so the lounge was a god send. I actually liked it but the furniture is continental and not to everyone's taste.
Photos and info by this link: the photos make it look more basic than it is.
