Tokyo language school advice- ALA, ARC, and Intercultural Institute of Japan

Hello, I am thinking about moving to Japan for a year while attending a language school. I've been taking a look at some schools through GoGo Nihon, and I've narrowed it down to: - ALA (Iidabashi) - ARC (Iidabashi) and - Intercultural Institute of Japan (Akiba). I was wondering if anyone here has been to any of these schools and could tell me a bit about their experience, and if you'd recommend them. I'm looking for a medium-intensity school so I could have the possibility of working part-time. Things like a friendly/chill environment are pretty important to me as well, since I've heard some schools treat their students like highschool kids. Ty!
