My Malaysian friends who live in London like to go home at Christmas to see family, so needed to book a place to stay. On Air B&B there was a flat available on the ground floor of the high-rise building in Kuala Lumpur where the grannie lives - sounded perfect, apart from the mosquitos (you don't get them if you're high up, and they thought they could deal with that). Just as a precaution, my friend asked if her brother could check it out, which is against Air B&B's rules, but they said OK. He found the place filthy, with the ceiling about to come down in the bathroom, and a large dead lizard in one of the drawers, so needless to say they will NOT be booking, but some poor unfortunate might. Scary.
