Also Airbnb will refund up to 50% per night for each amenity listed as available but is not such as: inter-net not working, no hot water, no fire pit. I know they will do it because my guest was refunded 50% for one night without air conditioning (fixed day after reported)

Guests need to be familiar with the terms of service and their rights. Airbnb expects problems to be reported when they occur. What do you expect them to do after you’ve left? That is part of the reason for the 48 hour window after checkout is to insure timely reports.

This is the host’s home. I wouldn’t have appreciated the pro-Trump literature but she can leave it; I don’t have to read it.

As long as she is not requiring you give thanks to Jesus or participate in prayer for a beautiful location, she can express her thanks.
Anyone who is offended by a “give thanks to Jesus” or “praise Allah” or “Todah Rabah” or “thank the weather gods” really needs to think about what that is really saying.

You failed to notify Airbnb of problems thus not giving Airbnb a chance to find you more suitable accommodations or refund. Something about the review you left must have violated the rules because I promise you they would not have removed it. A host can’t have a review removed just because they don’t like it.
