I think you guys are forgetting it was 1947. It was a different time. I didn't see it as a stretch. In older movies I notice it happens often. People are let in into other people's homes and apartments without much regard for who they are or why they're there. I know it's a plot point but I see it so often I have to assume it was being done and acceptable in real life. Trying to sneak someone in, now that would be looked on with suspicion.
Susan presented herself as one of Nugent's models. Think about it. He probably made previous arrangements for his 'model's to be escorted in quickly so as not to draw attention to the fact young women were frequenting his apartment. Surely the building wouldn't want other tenants to get the impression this was not a decent dwelling and they were condoning such activity. Management retained a key, so the tenant would never really know when they'd come barging in to make sure everything was above board.
The kid is also trying to impress Susan and win favor with her. She seems innocent enough so he wouldn't have had reason for concern. What could she do? Whoever the guest was, it might have even been seen as a courtesy to the tenant to have their guest wait in the comfort of their space rather than hanging around standing in the lobby.
Theirs was a very different mindset. Even in today's climate, someone so harmless looking, who claims to be a business associate might be let in. We assume buildings with concierge or door service has special security but usually the people are there for convenience; to greet and announce guests; to let people into the space; to retrieve things the owner may need, to arrange other services like cleaning, etc.
Homes in which there are servants, people were used to having servants in the home. These people managing apartment buildings and other residences should be seen in that context not as security. Instead of being attached to one home, they were shared within common spaces. As we know, most residential staff would do the same; let anyone in. They might also assume the mere fact they'd encountered someone; someone knew they were or had been there it would prevent them from doing anything illegal. As I said, it was a different time. They would be more concerned about being raided by the vice cops rather than worry about other crime which was more rare.

While you make a number of valid points, it seems to me you are over thinking it. A famous artist as Nugent surely was would have a lot of wannabe's trying to make his acquaintance. All the more reason to ensure the bellhop is one who can be trusted not to have his privacy violated.
I would still have him fired no matter what time period it was.
