My Mum learned this language along with German from a German missionary. I think the language sounds cool but I don't have much use for it. Why are you learning it?
I spent a wonderful holiday in the south of Tanzania, but it was nearly impossible to really connect to people. So I decided to learn Swahili a bit and then come back. This year I visited Kenya and could at least greet people properly and order coffee in Swahili, which is appreciated very much. I even gave my first speech in Swahili, to thank people in a Samburu village for their hospitality. I just go on learning. Swahili is a beautiful and rich language and definitely not easy to learn. If you love the eastern part of Africa, learning Swahili is your best option I think. No chance to learn all languages spoken in the various tribes.
