Pablo,
I'm really not sure what's going on with your page. Everything does look correct, but obviously Facebook can't see anything proper about it. Also, when I run it through an HTML validation tool, it's saying that nothing was returned:
validator.w3.org/check?uri=http%3A%2F%2F...ctype=Inline&group=0
Specifically:
Line 1, Column 1: end of document in prolog ✉
This error may appear when the validator receives an empty document. Please make sure that the document you are uploading is not empty, and report any discrepancy.
Also, when I use Pingdom to fetch your page, it's showing the file is 0Kb. Pingdom isn't always reliable, but combined with the above, something seems funny:
tools.pingdom.com/?url=http://www.turism...r=1&type=0&save=true
You may want to try your site from other computers or have friends in far away places try and see what they find. I'm not sure if there's an HTML error on your page, or if Facebook, Pingdom, and others simply can't see your site. This may also be caused by a server configuration error that isn't sending the page to 'robots' or other services, which while common to not allow some bots, it shouldn't deny everything that isn't a browser.
Hope this helps get you started, but please let us know if you figure anything out.
Thanks,
Alex
