Hi- My friends said they don't really want to rent. However, they know of another place: Casa de Escuela on Mirador beach for $600 a week. (maybe you could negotiate lower for a month). They say:
The place is owned by a couple from Vancouver, but as far as we can tell, it's managed by a guy named Steve Utter - Beach Dream LLC - 480 636 0675 - or - 1 866 798 2120. It has a tiny living room/dining room with a fireplace, a compact kitchen, plenty of closet space and master bedroom with a king-size bed and second bedroom with a bunk bed. There's another bedroom off the courtyard with a queen size bed and 3 piece bath. The garage is handy 'cause you can secure your vehicle. There's a TV - not sure about satellite.
I'll keep my ears open, see if there's any place else for a better price!
