Ask HN: Please help me find out the major flaw in my last project

[Dauntless]

I've done several websites in my lifetime but this one is proving to be the hardest yet.

It's not a problem to change or work to add something new, I've redesigned the website several times now. I've never done a website for apartment rentals before, but I didn't expect it to be this hard. It didn't convert any adwords potential user until now (i.e. visitors don't book any apartments), and I need to find out why. I believe there is a major flaw in it but I don't seem to figure out. The website is:

I would be very grateful for any type of feedback. Thank you, dear HN.
