It's almost as if there are different conflicting interests in one country... AirBnB/Booking, mass tourism, influencers on TikTok, tourist landlords, companies buying up flats expressly for tourism, individuals renting out their holiday flat, government, etc...

It's actually very simple. It's ES gov to blame, they have powers but failed to regulate housing due to own conflict of interest.
If there is any problem on any subject, it's always easiest to blame outsiders. Been done for centuries.

The main issue that needs solving is the lack of housing, and short term letting is consistently making the problem even worse by enticing investors to take regular apartments off the market and convert them into "holiday" lets.

It's terrible for the residents too because they get randos in their building all the time instead of regular neighbours.

I would take a page out of Singapore's book and get rid of holiday lets completely. Problem taken care of.

And then I'd go a step further by taxing the living daylights out of properties owned by non-residents as well as multiple property owners. Maybe introducing a very heavy property tax based on estimated value but giving all residents a 99% discount on a single property if used as their primary place of residence.

The government is aiming this at the AirBnB owners who have not registered. From what I can gather when advertising their property on AirBnB and Booking.com they should be listing a licence number licenced and many are not doing this which proves that they are not licenced hence the current push. It is part of a law that comes into effect on 1st July so I guess that there is going to be more and more action being taken. Spain is actioning this but I think that it is an EU rule so other countries will no doubt follow suit.

To be honest its both the owners and AirBnB's fault, no matter which country the owner comes from.
The owners are trying to get around the law that says they have to be registered and Air thingy ask for one but dont care as it brings money in and all that happens is they remove your listing.
The EU itself could fine the company millions, but I expect (cynical me) that lots of them own multiple properties and dont want to rock the boat.
The Spanish Gov, could easily check the owners details as I would assume that they are all paying tax on the earnings from such things. (opps silly me).

Benidorm is committed to build lots of new mixed use buildings all over 20 stories, each with rental and residential in the same building.
Cant wait to see what happens if the law is ever changed to stop mixed use (if it ever happens).

There were a couple of Air things in the village but they have all had their licences revoked as it is considered to be a residential area only. There are two new hotels not that far away, with another on the La Nucia Sports area being built (as well as the one that is still not finished).

Out of principle I wont use Air but instead book through Booking and ignore the listings with 'private host' in the description. My daughter stayed in one in the Cotswolds in April and she was charged a £80 cleaning fee, even though the instructions at the place stated they must empty the bins, strip the beds and tidy up. The hoover even had a sticky note saying "Use me".. I kid you not..

Ive just looked at two private listings in my local area and neither of them have a tourist licence number listed anywhere on the page. One of them has been renting for 8 years and is a top 10% listing.
Its €40 a day plus a cleaning fee of €25 and another €38 service fee. The local hotel with free breakfast charges its rooms at €46 including tax on booking per night.
Why would anyone pay these sorts of rates???

Hotels can be a headache. I stayed at one last summer in salou where people were putting towels down on sun loungers in the morning. Said to my self I’m not going through that again.
