@Mara1345 Ignore Airbnb 's price tips completely. They have nothing to do with a fair price for your listing, they are designed with one thing in mind-to get hosts to drop their rates to absurd levels, a race to the bottom, so more guests will book and Airbnb can collect their service fees.
Airbnb doesn't "adjust" the price tips upwards just because you aren't a brand new host anymore.
You set your price to whatever you feel is right.
And don't acquiesce to guests asking for discounts- guests who ask for discounts are red flags and if you agree, they usually turn out to be bad guests in other ways.
