Don't know about the MV Serengeti but MV Victoria was great, comfortable bunk beds, shared toilets but not too bad and pretty good food.
I have also traveled down Lake Tanganyika aboard the MV Liemba which was just the most amazing 3 days. This year I am hoping to catch the MV Songea up Lake Nyasa!
Enjoy your trip!

The MV Liemba has been on lease handling refugees from Burundi for the UN refugee organization for the past month or so. Since the Liemba is just one of the ships operated by Marine Services Company, Ltd:

With the Liemba out of service they may be changing the schedules for other ships in their handling.
The Liemba is supposed to be returning to her previous schedule according to a Facebook page.
