This topic has already been covered on the Forum if you look down the first page you will find it. Here is a great link with the form translated so just print off a copy fill it in yourself and either take it to the address in Alicante city or do it through the Post Office. https://www.spain-holiday.com/rentalbuz ... -community
A couple of things I see on the comments section of the website above
You can send your application from the UK by post to the office in Alicante just make sure you have attached a copy of your passport. Also if you don't have the habitation cert to hand to attach it you simply declare on the form that you have one .
It is up to yourself to decide the category your accommodation falls under
Make sure you include your NIF number on the I.D Reference section
In answer to the question about reporting to the police names and passports of the guests?
the reply is:
"yes, you have to register with the Guardia Civil, they will give you a number and log in details to their website Hospederias Civil and a registration form which you photocopy, when any client over 16 yrs stays they must complete the form, you must take a photocopy of their ID and then register them on the website, you have to keep all the registration forms in a folder, that they check periodically, if you havent done it, and they come for the check, you will get a hefty fine"
Also in order to get the log in details from the Guardia Civil you have to present yourself in person with your NIF Cert to verify who you are.
