I had a great experience with CET Taiwan! Academics (through the International Chinese Language Program) were rigorous -- expect to work hard, be engaged in classes, and see your Chinese improve significantly over the course of the semester. I also spent 10 to 12 hours per week at an internship placement that matched my interests. Although this made time management more challenging, I found the internship to be a rewarding part of my semester abroad.
Accommodations were comfortable and well-located; we shared student apartments with local roommates, who were super friendly and helped us navigate life in Taipei. Overall, Taiwan is a fantastic place to study Chinese. It also offers convenient public transportation, delicious street food, and plenty of things to do on weekends, whatever you're interested in. Just be prepared to be busy! If you're self-motivated and adventurous, this is the program for you.
