Yes, we did offer you early checkin and we did offer to do your laundry: we are glad that you noted that our cottage was clean and the beds comfy.
We have absolutely no idea what you are referring to regarding the "price of $500 a night". At the height of the summer our rate is just under $200 a night. There is an additional charge of $25 after the first two guests, so in your case that fee applied only to your third guest. I will contact Airbnb to see what occurred with your reservation, as Airbnb certainly did not pay us more than double our usual rate.
p.s. regarding the "old couch": my daughter is a college student who was home between semesters and had just found a perfect couch for her apartment..... the couch you saw was upside down because it was being moved the day you visited. As our Airbnb listing indicates, we have an "Old Malibu" property with all of the requisite charm -- and also the eccentrics -- that go along with that. If you read our previous reviews, you will see that our guests are almost always delighted with the experience of staying in a unique, family setting. Next time, we hope you will find what you are looking for. Certainly if you have budgeted $500 per night you might be happier choosing a more traditional hotel experience. Take care and good luck and safe travels,
Jennie and Carol
