Hi Linda xx,my suggestion is to look at the major Spanish newspaper in the city you plan to live in. Look to rent a room in a private home with a nice family.I live in Lima Peru but in the past I lived in Honduras in which I lived with a family in a rented room.

A better suggestion is to enroll in a Spanish language school and take a weekly course and in addition,enroll in the PRIVATE HOME STAY where the school will place you with a nice family for the week you are studying Spanish.
There you will have a private room with a bathroom,meals and be able to make friends with the family.

It maybe costly but what you can do is (before the week is over) make a deal with the family to pay room rent monthly without the school.This is up to you.

I did this in Honduras and I didn't feel alone.If you need more suggestions,you can P/M me.I hope this helps.

Tony
