Is this website legit?

People seem to be saying thailand is more expensive and scoff at people trying to live under 1000 usd budget because airbnb is expensive and whatnot.

But this website seems to have pretty decent apartments in bkk and chiang mai for 5000-8000 baht a month?

Is there a catch? Could someone chime in who has good or bad experience with the website? Why are most people defaulting to airbnb or hotels, if this website has such reasonable prices?

Thank you, hopefully youre having a good day :)
