The following is a copy of what I sent to the host. Make your own conclusions fellow traveler.
A few suggestions for future guests;
Clean the stove extractor
Change the broken black sofa
Change the old ragged white dining room chairs
Add the barstools as depicted in the photos.
Repair the door frames
Paint bathroom to cover the greasy, gross streaks on the wall
If you have 4 tv, they should all work.
Paint walls to cover all the scratches, shoe marks and scrapes.(specially the ones at eye level).
Don’t expect your guests to be there while any of this work is being done.
Change saggy mattress in the master bedroom
Get new bed spreads
Replace the broken light bulb
Fix the glass in the kitchen cabinet before you have a serious accident
Add a handle to the pullout cabinet in the kitchen
Clean the grime and junk on top of the refrigerator
If you really want to get fancy you could hide all the cables for the tv
