I've been asked to pass this on.  As it's very sensible advice I am happy to do so:

It is always sad when someone dies. It is often daunting to deal with the bureaucracy in your own language in another language it becomes a nightmare. Here, writing a Spanish will costs around 40€
Gaspar at Notario Carpena speaks perfect English and is happy to guide you through the process.
Please all expats… “just in case” write a will here …your last testament will be lodged with the central register so you wont even have to remember which notario you used. It will save your loved ones so much stress, difficulty and money. Please excuse the macabre subject but to exchange important information I think is to the benefit of all.

I would add that I haven't used Gaspar so couldn't make the recommendation myself but I'm sure there are plenty of notarios who can do the work.

Very Important, that people living here do make a Spanish will.
Even if they have already made one in the U.K.
Not expensive to do this here, and could save a lot of hassle, for loved ones!

we did ours 10 yrs ago when we bought our first house  :)
