I've once stay at USJ 3 (opposite of summit , beside petronas station) for 1 week, because my college's management finding hostel for us. We lived there 1 week. When I went it, it look so spooky and fugly. There has 1 piano in living room, and upper floor haz the curtain which is fell down wan. It looks so old already, but we have to stay there for 1 week. We lived there and nothing happen. We have around 9-10 people staying there. While waiting for the management to complete the contract for a condo. But the next batch of my coll's stay there after us, only two of them stay there for few days, they say at night they can hear noisy at down stair (just like got thieves break in or something) then both of them go check, nothing there also. And some of them say the piano knows to play automatically sometime
