If you don't mind living with someone who might have strange interests or ulterior motives than by all means, find yourself a flatshare. We tried it out the first couple of months we were here and although it does cut the rent in half on the island, it's a total crap shoot. The particular place we found was situated in an ideal location and had a great price. Once we were there for a while, we discovered the flat was infested with roaches and the person we lived with literally emptied half a can of Raid on one roach, making life totally miserable. To top it off, she used the extra room as sort of a side business to make money off of expats. Not by charging higher rent, but by tacking on all these extra charges like cleaning, supplies, and other shit. Bottom line is: caveat emptor!
