I will also be in Malaga at a language school for close to a month this summer. I went last summer also. I found malaga to be pretty safe overall although I think the beach area is a little safer then el centro. Most of the schools are in el pedragalejo which is a 5 minute bus ride from the city center. In my opinion, Malaga gets a bad rap. People always say it is a town to be skipped and granted there is not a whole lot of sightseeing opportunities there but as far as a place to live for a while I think it is great. The people are friendly, the city is easy to get around, it is inexpensive and a short bus ride to many of the must see cities in Spain. Do you know what school she will be at?
