Angela, I think you have got the best outcome you could have realistically expected.
@Elaine701 has summed it up well, Aircover is not insurance it is just a re-branded Host Protection Scheme that has been around and criticized for years. About the kindest way to describe it is.....it's a bit of company goodwill!
But you must also appreciate Support have a difficult time in assessing how to handle claims. Not all hosts are totally honest.
I have mentioned this on threads before but I once had to deal with a claim for a damaged outdoor setting. The guest had damaged 2 of the 5 seat covers with cigarette burns, and the covers were no longer replaceable. The host did all the right things, supplied ample evidence of the damage with stamped dates indicating when the damage occurred. He submitted invoice estimates for a replacement outdoor setting.
He did supply a purchase receipt for the original outdoor setting but closer investigation with the receipt supplier revealed the receipt was not for this purchase, was a copy and had been 'photo-shop' altered! He had in fact paid $270 at a local charity op-shop for that setting he was now claiming $2,500 in compensation for!
Where does support draw the line?
I think your case is relatively simple Angela......it's a sink, it's easily replaceable. Where it would have been a lot more difficult, if the countertop had been damaged. A sink is one thing, a $7,000 + countertop is another thing entirely and I think you would have struck a far higher hurdle for settlement with that than a sink.
Best to take out adequate STR insurance that will cover you for major damage and build just a bit more into your nightly listing amount to cover minor costs, and just treat Aircover for what it is.......a possible bit of company goodwill!
Cheers.........Rob
