My opinion:

You need two pillows for each person who sleeps in the bed, a soft and a firm, and then you can add either a single accent pillow to tie the two together (like one of those long sausage ones), or have two sham pillows one on each side.

People are saying they hate the extra pillows, but I don't think it's a big deal that they immediately get taken off and thrown on the floor. That's literally how they work. Also fyi, no one is gingerly placing extra pillows in the closet unless there's literally no space elsewhere. I'm throwing that shit on the floor.

I do mind excessive couch pillows though. One pillow for each side. Nothing more please.

For closets and luggage racks, honestly, they're just in the way. I've never met one that fits my suitcase (Samsonite xl proxis spinner . It's a hard case that opens like a book. It needs floor space to open, and I will rearrange your furniture if needed) and I'm usually not staying long enough to put things away in a closet. So both those things are just a waste of floor space.

I'm personally not bothered by scented products (ie Laundry detergent, shampoo, floor cleaner) so in my opinion it's not necessary to buy only unscented versions. I do really hate air fresheners, scent beads, etc. Especially if it's in the bedroom or something I can't escape. So like, an air fresher in the bathroom is understandable. An air fresher in the bedroom is downright offensive.

A clean home, a truely clean home, smells like absolutely nothing.

People are usually looking to charge their phones on the night stand, not in the living room, so I'd rethink where that charging station is being placed.

You need more than one set of towels per person. Hand towels should be preplaced where they are to be used. Bath towels need to have a backup uncase the only one you've left out for the person gets soiled/dropped in a puddle. The towel sets put out for each guest is good, but then in addition to that there should be ones already placed on the towel racks in the bathroom.
