Hi Marymootoo :)
Webs - http://www.webs.com - is a great place to start. It has a simple to use builder tool that allows you to easily create a professional looking website. You can add images, text, slideshows, videos, e-mail submission forms, social media modules, and a lot more. The best part is, you can do all of this for FREE! There are also premium features that you can pay for to further the quality of your site.
I think in your case, this would be the perfect solution. You can create some relatively simple pages that list your cottages and the prices. The slideshow and table tools would be great for this!
As far as getting it ranked on google, there are a number of ways of going about this. Webs offers some built in tools for the purpose of SEO and and reviewing your analytics, but also goes a step further by providing you free resources to consult. The small business center - http://www.webs.com/small-business/ - has some great advice as well as the blog - http://www.webs.com/blog/ (hint: seo and content marketing strategies are key).
Full disclosure, I currently work for Webs. I do, however, truly think it is the perfect place to start for anyone who doesn't have website building experience. The process is greatly simplified and flexible enough to suit most peoples need. I'm more than happy to answer any questions I can regarding the builder.
Hope that's helpful,
