Hi @Meg143 Welcome to the community!
The bad news is... if your guest reviews you then, after 14 days it will be public regardless of whether you review her or not. The good news is... you might have had a proper grown up guest who realises she is high maintenance and could give you a good review after all.
Expectations of guests staying in accommodation expect higher standards than when they are staying at home, and that you can't get away from. If there's any way you can raise your game to cater for these types of guests then it would be good for you in the long run.
Mold smells indicate some dampness somewhere, so find it and dry it, then keep it dry. Air the area as much as and often as possible. Wipe or vacuum the dust - or both. Our vacuum gets more use than it would normally after vacuuming down the sides of wardrobes, tops, behind beds, the corners of rooms, chimneys, window sides - everywhere. And it takes time.
Take on board what your guest said, try not to worry about it and try to improve on those areas she mentioned, then hope for a more understanding guest next time.
Good luck !
