If you want to go to Tanzania you should absolutely stay with VIT. It is great to be with the other volunteers so you can share your experiences. I did for 6 weeks volunteer work at the kindergarten in Sakina. It was such a lovely place to be around and it was so hard to say goodbye to them.
The school is small with only 2 classrooms. This makes the whole project very personal and makes it so easy for you to get in contact with the teachers and children. I am sure that you are gonna miss all of them when you leave and to volunteering work there.
It was such a great adventure with crazy happenings, I am sure I will come back.
Thank you for everything!
