What are some bad Language schools in Tokyo?

I'm just curious if anybody knows any bad Language schools in Tokyo so I can avoid them. I plan on attending Language school in July. I really only know hiragana and katakana and a few basic grammar points. I still plan on studying all the way up till I move to Japan in June. Currently I submitted an application to Ala language school through gogonihon and waiting for the person helping me to give me an update on my application. Here are the list of schools that I plan to apply to.

Sendagaya Japanese Institute

ALa language school

Shinjuku Japanese Language Institute

yosida

Yu Language Academy Tokyo

ARC Academy Tokyo & Shinjuku

ISI Takadanobaba

Japan Tokyo International School

Sendagaya Japanese Institute

If anyone has attended any of these schools or knows someone who has attended them, please let me know their experience with them. I picked these schools because I want to live in Shinjuku when I move in June. All of these schools are either located in Shinjuku or Shibuya so I don't have to spend too much time commuting in the morning. Also if you know any good apartments that are foreign friendly please let me know as well!!!
