I'm not sure that I perfectly understand this. Where I come from, a lounge is a room in a house: bricks and mortar. You could have a 'Lounge set' ie. sofa and 2 armchairs, but it's a very old-fashioned phrase these days. She isn't living in a lego house, is she?
Maybe she runs an airline? Otherwise I agree, this doesn't seem to make sense in English...
That was my first thought. I`m having to double translate - I would call it a living room or a family room, and then to see someone buying one?
I could imagine this to be a short way of saying she bought a complete new set of furniture for the lounge, but it's a bit odd isn't it?
I know that they use "lolfa" for the lounge in a hotel, but if you have a hotel how could you possibly buy a new lounge (i.e a new room) for it? Building one, yes - but buying one???
