You clearly have never been outside the touristic city centers if you think "Portugal has preserved beautiful human-scale cities and villages" or actually seen the massive destruction caused in any place that had even the most token amount of potential for Tourism were masses of skryscrapers were built (like in Albufeira) or just enormous beach or golf-resorts, or even the city centers were the locals were kicked out and the local businesses died because when every dwelling was turned into an AirBnB, those little neighbourhood shops selling everyday things lost most of their clients.
I'm sure living in the typical "beautiful" 8-story building from the 80s (with such horrible energy efficiency that its significantly colder indoors in Winter than in the equivalent place in Northern Europe) 1h away from the city center were the typical 30 year old lives with his or her parents because they can't afford their own place with the shit salaries they get from the only kind of work they can find - invariably a short-term contract - even with a bloody degree, makes them feel happy and all nice and warm inside (and people definitelly need that inside warmth when the house reaches 11 C indoors in Winter).
In one of those "horrible" cheap chinese appartments you really can't enjoy the beauty of the 80s-style fly-by-night-builder appartment built at a time when there were pretty much no building rules, in a residential neighbourhood with insuficient public transportation and having all the freedom and privacy you have when living in your parent's home in your 30s.
That chinese nightmare is horrible by itself, yet it's great by comparison with the even bigger nightmare created in lots of countries in the West as governments and central banks turned the housing markets into a money making machine for rentseeking investors, screwing everybody and anybody who wasn't already a realestate owner when they started doing it, so mostly the young but now things have reached such a bad point that small shops not in prime touristic places can't even afford to stay open because their rents have become crazy.
Sure, it's a fucking "paradise" out there for retired owner-occupiers who have cashed in on their overvalued house in the city and moved to the countryside. For the rest, not really - even young adult owner-occupier couples wanting to upsize because they would like to have children (and a 1-bedroom appartment won't do) can't because they can't afford the money to do so: their 1-bedroom is worth a stupid amount but the 2-bedroom is worth a stupid amount too and now they can't afford the difference.
(Unsurprisingly birth rates in Portugal are low and falling and it's now one of the 10 most aged countries in the World)
