Hi Catalina,
I just did a Google search for a couple of the hotels on your site and you appeared on the first page of results.
Have you set up your site with Google webmaster (search console) and submitted a sitemap, I would also do this with Bing and Yandex.
I would also set up a Twitter page, Facebook and LinkedIn page and then link them back to the website.
I would also have a blog page and post local news/events information about the area, ideally one a week, this will keep a regular feed going out about the site.
If you use a plugin like Jetpack you can auto send a blog news post from your website to all your social media platforms – saving you time and only having to write something once.
Just a thought 🙂
