I roughly measured the area by counting my steps, and it comes out to about 325 m² (around 15 × 23 m), give or take 10%. With that size, I don’t think the lounge can offer very much.

Once you factor in a reception area, bar, showers, coffee machines, buffet, workspaces, and seating, there won’t be much space left. People will likely have to sit quite close to each other. I also suspect the food will be similar to what’s offered in the Sala lounge, so some passengers may end up going back there instead.
