I cannot comment on the quality of the teaching staff but only as a Homestay family.
If you are thinking of becoming a homestay family I would not consider this school. They are extremely disorganized, unresponsive and dismissive of feedback when provided not to mention they are tardy in paying the families. If notified of their shortcomings they will be apologetic but sadly nothing gets done to improve their operations. This school has really gone down over the last few years.
I have had repeatedly great feedback from my students so you would think they try to keep on top of their homestay families needs, especially with those where they have minimal complaints if any from students.

Again, if thinking of being a homestay family and believe me there is a huge need in the city so you really can pick and choose which school to work with I would not recommend GEOS.

Unfortunate I have to sever my ties with this school but it has become an administrative nightmare which I did not need.
