Lynton hotel for three people in one room?

I posted earlier about traveling to the UK with my daughter, turns out my son is going to come along as well. I've seen a fair amount of positive feedback on the Lynton Hotel in London, though everyone comments on the rooms being small. To their credit, the folks at the Lynton did warn me that the triple rooms are "cozy". We don't mind small, we will only be there for three nights, but feedback on this would be most appreciated. Thanks!
