We are very disappointed to see the review of our stay. As a business transaction, we would like to keep this professional and you have made this personal, which we did not expect in a business transaction.

We did not receive any payment request from what we saw in the email history. In checking our email history, we had indicated 3 adults and 2 kids. Not sure how you can say we under estimated after the initial request. The response we received was for 3 adults only. We paid for the request, as we thought kids are free. Upon arrival we where indicated additional 20 for each kid, which we assumed will be deducted from the deposit.

So if we keep the apartment squeaky clean, why do you get cleaning fee?

You also had the security deposit. You could have sent a simple mail, with details and kept whatever money was applicable and return the rest to us. That could have achieved what you needed. This looks to be a very simple problem made big. Not sure what your real concern is to make these things big.
Please let us know the real concern, and we will address it.

You can check with our previous renter on Airbnb, for your comparison.
If there is anything else we can do let us know.
