Humanitarian work in Kribi (Yaoundé)

Hello All !!
I am thinking about taking on a Econ Dev humanitarian position based in Kribi city. Although I do not have a salary, housing is paid for and a modest allowance of appx Protected content is given per month.

I can manage money well but can I even survive with that? Heard Cameroon is quite expensive.

Thank you all for your help!

p.s. any other important info is welcome :)
