I'm considering taking some time (6-12 months, probably) to live and work in Puerto Rico (or perhaps Peru, Costa Rica, or Columbia), and one thing I'm having a hard time researching is a rental home for my family. Most of what I've been able to find on the internet is short-term (rented by the night or week), vacation-oriented, and generally very centrally located in San Juan or a beach city (and therefore expensive). Where do I find a regular house that isn't spectacular and luxurious, and not in a tourist-y area?
One answer I anticipate is something along the lines of "you have to go there, speak Spanish, and look in the local newspapers and signs in windows," but that isn't going to help me much here: I need to have a decent idea of what's available before I load my family onto a plane to go there, and I speak only enough Spanish to ask for a bathroom.
