I studied abroad in Florence at LDM for spring semester 2018. The Athena staff were really friendly and it is a small company so you feel like you're important to them. The only downside of being a small company is that you don't get to know the people that you're going with beforehand. My roommates all went through their school's programs, so they knew a lot of people who were going beforehand.
Florence is a beautiful city and Italy is a great country to study in. I recommend traveling EVERY weekend or as much as you can because the semester does go by really fast. I also recommend the LDM field trips that are included with Athena's program. Everyone else had to pay $300 or so, but I liked that mine was included in my tuition. I definitely recommend the Amalfi Coast trip, but DON'T miss the bus!
LDM is a great school for many programs. However, their policies are not the best. You can only miss 2 classes before your grade goes down and if you miss 4, you automatically get an F. If I could do the semester over again, I would have studied at a school that is more lenient with absences.
I LOVED Florence and everyone I met there and I would definitely recommend studying here to anyone!
