In my heart, I'm a neat/clean freak but I just don't have the energy to do it. Plus, I'm learning to overcome mild hoarder tendencies.
So as a host and as a guest, I expect: Clean sheets on the bed, clean towel, hand towel, face cloth, vacuumed floor so it isn't gritty or cat hairy underfoot, clean bathroom - toilet, sink, shower enclosure, the entire place reasonably picked up, even if that is just shoving everything in the 'hoarder' room and shutting that door.
Additionally, when I'm hosting, I do my best to provide the basics - coffee, cream, breakfast fixings, snacks - and I usually have extra toothbrushes on hand and I don't mind if people use my toiletries as I have one of those dispenser things in my shower with shampoo, conditioner, body wash and facial cleanser. But I don't expect other people to provide these things.
