Nihongo Hiroba for learning Japanese

Hey guys, I am beginner level at Japanese(know about 200 kanjis, conversational level for basic stuff, grammar and vocabulary medium), looking for free/cheap Japanese classes in and around Shinagawa. I found a place called Nihongo Hiroba in Shinjuku multicultural plaza which is free of cost and no registration required, you just show up at class on time and that’s it. The time of the classes really suit me so I was thinking of attending classes there.

Has anyone else gone to their classes? How was it? Anything I need to know? Or I am open to any other classes near/within Shinagawa or around shibuya/shinjuku area, please let me know.
