Does anyone know about half-decent and B&Bs in Uxbridge?

Have applied for a full-time Masters at Brunel, but I live in North London. Either I'll have to commute two days weekly, or I could stay overnight between the two teaching days. As the commute will be costly it might well be cheaper to stay.

For personal reasons I can't move house.

There is a small chance that I'd be able to stay with my friend's nan, but she's quite elderly and I don't want to impose. And am waiting to hear back from accommodation office re: only staying one night. So where else could I stay?

Any genius ideas?
