@Lawrene0 I was going to post something similar. Hosts should resist the urge to over-decorate. I always figured guests basically appreciate bare surfaces, and not feeling like they are living with someone else's knicknacks, which they probably don't find nearly as attractive as the host does.
They aren't impressed with the host's dried flower arrangements and "collections"- they just want to have adequate space to put their clothes, their books, their laptop, etc. without having to move things.
Art on the walls, color and pattern in furniture and pillows, cool paint jobs on the walls, some small throw rugs, can all be used to keep the space from feeling barren.
Aside from the lamp on the bedside table, a very small vase of freshly cut flowers and greenery from my garden, and a few local travel books, there is nothing on any surface in my guest bedroom. Their bathroom counter is much the same- a pump container of liquid soap, a hard plastic container to keep their own products in, so they don't slime all over the counter, and that's all. There's a small basket of "help yourself" products on the shelf with the clean towels.
When I lived in Canada, I had lots of houseplants, but living in the tropics now, with lush green views out every window, I don't do houseplants anymore. Watering chore off the list.
