BestSpainHolidayRentals.com is available.

Although in the past having a keywords in your domain name helped ranking, Google devalued Exact Match Domains last year, see http://searchengineland.com/google-emd-u...

Here are a few tips, choose a domain that includes your keywords and the area you are covering, choose a brand name e.g. homeaway and avoid hyphenated-domain-names.

Spanishholiday.com

well one user posted both URL's are in use so staert thinking specifically using keywords in URL to name your website.

it's for spanish people rentals correct?

villarentals.com holidayvillas.com

apartmentovillaria.com or .net or .dot whatever else can be used

Spanish holiday because that's your keywords - helps with SEO

Those two urls have already gone, and would cost your friend a bomb to buy.

A friend of mine is setting up a website to promote villas/apartments to rent out in spain for a holiday. Which is the better website name to have....... goingonholiday.com or spanishholiday.com??

Any feedback is much appreciated
