Have any of you ever worked at, currently work at, owned, or currently own a bed and breakfast? Or at least stayed in one?

I’m designing a bed and breakfast for my college Senior Thesis project, so I’m trying to conducting research.
Is there anything you liked or didn’t like?
Is there anything you would’ve changed about the space, design wise (i.e. size of the rooms, ease of travel throughout the building, lighting, etc.)?
Was there anything that could’ve made it better?
What is/was the greatest difficulty in owning an business like this?
Feel free to add anything else!
