In my own mind, if I'm paying for the room, then I get the bed that I want, and my friend gets what's left. If he's not happy with that, then he is free to pay for his own room and get the bed that he wants.
But I've learned to set expectations to avoid surprises: "I'm going to redeem points for a room. If you're comfortable staying in a sofabed, you're welcome to share."
