Did anyone study at LTL Japanese Language School in Osaka?

Hi !

I'm planning on staying 1 month in Osaka next year on a working holiday visa and I wanted to take Japanase courses. Most of the schools I found seems to be student visa factories focusing on jlpt and don't seem very interesting to me. I came accros LTL Japanese Language School but there is no review on maps, only a few on websites I don't know. Has anyone heard of them or study there?

Thank you 🙂
