I just had to spend time to send 3 messages to a potential guest that had NO official documentation of any kind listed with airbnb or any guests history.
AND if I don't respond within a certain time, MY RATING is penalized by airbnb. I don't have time for this !!! I DON'T want to hear from these potential guests at all.
EXAMPLE:
I'm sorry Javiar, You are not properly registered with official government issued documents to be considered eligible to rent apartments through Air BNB. You also do not have any guest history with Air BNB, so we will not consider you to rent our apartment. I am sorry, but this is an official policy.
Please forgive the terrible translation, but I don't speak Spanish well and I am using google translation.
