I'm completely baffled about your reaction.
The missed calls and texts you speak of were well past midnight while i was asleep. i have the screenshots of this. When i opened your messages in the morning i saw that at night you had written me you had lost your keys, and close to the morning you had found them again. There was no ''all weekend trying to reach me'. You tried to reach me at night (one night).
Second: The checkin time was clearly stated, however i had to wait 2 hours for you to arrive, something i did happily at the time. The checkout was also clearly stated to be 12 o'clock at noon. You checked out much later. Again i did this happily for you, which makes it all the more unreasonable to get this review from you.
I do hope with other bookings on airbnb you yourself communicate better about check in and out times and realize that when you lose your keys at night that is your responsibility. (Even though had i seen the calls i would have gladly come to help)
