I thought i replied here…
Get to a locutorio (internet cafe) as soon as you are there. The people there are ussually foreigners (or at least quite a few of them…), young, and not having enough money to have internet at home (IE, looking for a room mate.) Plus, they almost always have some kind of messageboard there.
Talking to the owner might help as well…
( always ask spanish people if they “Entiendes Ingles” (understand english) and not “Hablan Ingles” ( speak english) Half the people understand it quite well, after that a piece of paper and a pen does wonders….
