The host forgot to send the keypad passcode to us, so we have to wait in front the house for hours at night. With the help from Airbnb customer support team, we finally heard back from the host. Host explained it's one-off and I can believe it.
Regarding the stay experience, the house is clean. the amenities is not the best and get the job done, except there was no duvet for the bed but only a blanket. We both woke up at night because it's too cold and have to turn on the a.c. and the running a.c. is noisy so we didn't get a good sleep. so overall it's a disappointing experience.
