@Brandon387Everyone was new to the platform once. There are no specific red flags on the listing for me. If you're feeling uncomfortable, contact the host and ask them some questions. One of the usual red flags for fakes is generally a too-low price: does it seem overly cheap when comparing it to the competition? The house does appear to be real: see https://luxurygetaways.co.za/. There is never a guarantee the images haven't been stolen, but it should be easy enough to verify that.
Personally, I don't think I would be comfortable booking a $900 a night place that had no reviews, but if you like it enough to take a chance, maybe you could be one of the first people to review it.
