I understand my frame of reference is much different, but I don't see how they can call this luxury. The plans I found show a single two-bedroom, one-bath unit on the first two floors, with a one/one on the third. Compared to the bedrooms, the living spaces are next to non-existent and the bathrooms are bigger than the kitchens. Yikes!
