semester study abroad in Granada, Spain

I don't know of anyone personally, but while in Granada on vacation, I met quite a few mother/daughter pairings where the daughter was studying abroad. Granada is a neat town and there are restaurants and shops. With the buses, she could visit Madrid or Sevilla and also there's an airport to fly to farther reaches.

Sounds great if she wants to focus on that region. But it's not an ideal location if she's trying to explore more of Europe every weekend. It's served by rail, but not a high-speed line, at least until they finish upgrading it. See train schedules for Spain at www.renfe.es or for all of Europe through the DB link at Looking Up Train Schedules and Routes Online. Destinations along the south coast of Spain are mostly served by bus (several private companies), not rail.

Granada airport serves a few domestic destinations, plus London and Milan, per Wikipedia and www.skyscanner.com.

It's about 2 hours by train from Granada to Malaga, with more flight options. Go to the wiki page for the Malaga airport. Toward the bottom, there's a table with all the airlines and destinations.

We met a group of young women at an ice cream shop when we were visiting Granada in 2015.
I conversed with one of them because my mom liked her purse & wanted me to find out where she got it.
I found out that she was studying at the university and was enjoying it so much so that she was in the process of finding out if she could stay 2 semesters, instead of the one that she had been approved for by her U.S. university.

What are her other choices?

If I had a choice, I'd probably choose Toledo, Sevilla or Barcelona.

Having said this, I'm sure your daughter can contact other students, from her university who have studied there, and find out the pros and cons.

When my daughter was looking for a study abroad program, she read numerous student reviews, contacted students who had already studied at the universities she was considering, made sure she would get the credits required for her specific major, etc, etc...

There's much to consider when choosing a study abroad program; guaranteed student housing, safety, university ranking, on-site study abroad program office available to assist the students in case they face any issues or emergencies.

There's much research to be done.
My daughter wanted to study in a country (which will remain nameless), but after reading multiple student reviews, it was clear that safety was a major issue, and she obviously chose a different country.

Good luck to your daughter in choosing a good study abroad program; one that will meet her academic requirements, as well as her desire to experience and learn about a different culture, and also give her the opportunity to travel :-)

Edit to add:
One of my sons also studied abroad, and the conclusion is that studying abroad is a very enriching experience and all students should consider, if possible.

Bill Clinton, I think, and he loved it.
