My 2 newfs were crate trained from the day they arrived home, they were both allowed free roam of the house while I'm at work when they reached ~18 months old (until they were trustworthy), because I am at work during the day I allowed them to sleep in the bedroom with me with the door gated (not in a crate). Taylor decided that sleeping on the cool floor was better for her but Splash likes to sleep in the bed with me, sometimes she's in the bed all night sometimes she on the floor in her favorite spot next to my bed. It doesn't bother me even as big as she is (110 pounds) - don't know what I'll do should I ever get married again
just my opinion but I would start out with a pup in a crate in the bedroom and once he/she is completely potty trained I'd let her sleep where she wants in the bedroom, and if you don't mind her being in the bed and she wants to be there then everybody is happy
