Ds1 is in private halls of residence (dwell) at one university and ds2 is going to a different university. Ds1 pays £125 a week for his and most rooms are the same. At ds2's potential university they are all very different rooms with very different prices ranging from £99 per week to over £200 per week.
I don't know whether it's worth paying more for nicer accommodation or not. Also ds2 has autism and selective mutism so don't know if he would be better off in a smaller flat or even a studio or would that be worse. I can't imagine him living with other students tbh, he struggles living with his brothers.
