Without seeing the actual listing, it's impossible to tell for sure whether or not it can be trusted
However, the answer to your question is yes, you should be wary of any listing that's less than half the price of others. Very wary. As for the 7 positive reviews - again, it's difficult to tell without seeing the reviews themselves, but the reality is, there are thousands of unscrupulous operators on the platform, that populate their "listings", with false reviews from fake profiles connected to their own accounts, so you can't rely on reviews as a reliable barometer of the "host's" trustworthiness either (especially with only 7)
So while it may just be a case of a new host pricing low to get the bookings, it's also just aa likely to be a scam. I'd find something else, if I were you. Not worth the risk.
