Spanish language learning programs in foreign countries with instruction and home stays recommended?

I’m interested in spending a week or two in a spanish speaking country and have looked into programs that offer instruction for part of the day and free time in afternoon evenings. Most offer the option to stay with a family. I am a beginner – intermediate and want to work with an organization that will place me according to my level, not just do what’s good for them to get business.

Can anyone who has had experience with this recommend a country/city, as well a particular company they did business with ? Thanks.

I have friends who went to Cuernavaca, Mexico for such a program. They took classes during the day and lived with a family. They loved their experience and want to do it again. Here is the link to the school:
