hi if you are in corralejo i recommend las marismas behind baku or suite hotel atlantis fuerteventura formally trendorado this pool is definately heated, it will be cold at night when you go so jackets are a must, las marismas has huge comfortable beds and apartments lovely only built in 2004 i think, we enjoy both places and go on a regular basis try travel republic for good quotes.
hope this helps liz
