This is a tough one @Jo102. You clearly try to communicate what guests should expect and they are not exactly paying a huge amount for a whole house so expecting a hotel type experience is a bit unrealistic. Unfortunately, a lot of guests expectations are unrealistic and a lot of them don't read the info you give them, or they don't take it in.
It's also really hard to make an unmodernised space look shiney and perfect. I have a very old house and although most of it is renovated/redecorated/nicely furnished, it's far from perfect.
What I realised is, although I have a weekly cleaner, there are so many places for dust to settle and things that you don't notice the cleaner isn't doing.
I know it's difficult when you have a family, but I would suggest a really thorough deep clean if you can manage it. I've been doing this room by room while my cleaner has been on holiday and I was surprised at how much dirt I found. Some of the skirting boards and corners really needed attention. The inside of the bath was pristine but the outside was disgusting. I didn't realise how dirty some of the kitchen cabinets were until I ran a cloth over them and they changed colour! Yuck! And to think I thought it was all clean (I pay for a cleaner after all).
If you can get the house as clean as possible, after that it is a matter of less rigorous regular cleaning. Do your normal clean, but each time, pick one thing/area that needs deep cleaning, e.g. skirting that you wouldn't necessarily do every week. That way you can keep on top of it.
