Learning in Sendai ?

I have been staying with my girlfriend in Yonezawa for the past few weeks and I want to study at a language school in either Sendai or Yamagata.
Has anyone had any had any experiences with any language schools in these areas ?

I found the Human Academy in Sendai has anyone learned at this school ?

Genkijacs and GogoNihon don’t have any schools in these areas.

Thanks for the input.
