Self-catering accommodation in Tsavo

My family and I will be visiting Tsavo in December, and I'm trying to decide between the self-catering bandas at Rhino Valley Lodge (Ngulia bandas?) and the self-catering bandas at Severin Camp. Has anyone visited these two recently? Any opinions on which is best? At the moment I'm leaning towards Rhino Valley, because although it's a bit more expensive, it seems to have better views and the bandas have their own fridges, while at Severin camp it seems there's a central fridge to be used. The up side to Severin camp is that apparently there's a swimming pool there which my boys would love.
