If you want your accommodation to be added, and you want it to be free, you will need to add a link to Ivelet from your website.
Then just get in touch using the contact form to say that you have done that... Contact Page. Or better still register and request a setup from there; this is better because there's a small form to fill in which makes sure that we have all we need to set up your site.
The text and pictures will usually come from your main website so do make sure that you own the words and pictures. We cannot use words or pictures from sites other than your own. If you do not have a site then you will need to send the text or input it yourself, which makes it yours!
