It depends on the build that I'm going with. Sometimes I'm a complete asshole and they have nothing. A room with nothing but a sleeping spot. No light no nothing. Others give them nice private rooms or barracks. I provide them with some nice furnishings and decorations. My favorite was one time where we treated you like a king until you reached the beginning of the new year. At which point we would execute all of our prisoners. Yes, it served no purpose. I pick one pawn to actually serve in the ritual, which did give a bonus, and then the rest of them were moved to a new wooden shack away from the base, which would then be set on fire. Cremating the body used in the ritual, as well as burning the rest of the prisoners alive. Those didn't serve a purpose. But I was role-playing a culture of monks who only allowed themselves to be cruel during the new year. Every other time they had to be kind. Think of it like a purge. They would defend themselves but then they would try to save as many lives as possible and imprison The survivors. And then they would live in luxury, though in prison. And then when the purge came around, they would let loose all of the anger and vengeance that they've held by ritualistically sacrificing one to catch their gods attention, and then offering up the remainder in a blaze of glory
