Genuinely curious - what would you refresh? There are structural elements that would require moving walls, e.g. expanding bathroom size, which I don't think are likely to happen. The carpet and furnishings are are old-looking, but I find them to be very well kept. The furniture is sturdy, and there is a real desk, real recliner, etc. I'd honestly keep this, even if the decor is no longer in vogue, than risk a "modern" redo that trades function for form (e.g. rooms with no desks which are becoming increasingly prevalent).

I suppose the common areas could be modernized, and maybe I'm kind of weird like this, but I find the muted, old look kind of comforting in a world where everything is ultra-modern, ultra high contrast.
