I agree thermal isolation is a bigger issue in Portugal though. Because really cold days are not that common, old constructions don't have proper isolation and rely on inneficient heating. In the UK however you have the opposite problem where almost no apartment is ready for warm days. A flat with air conditioning is a rarity. Last summer a friend of mine moved with his kids to a hotel for a week during the heat wave just because of this.
I do agree with you on air conditioning in the UK though, for sure.
I'm in a rental for this month, and I just woke up to this - noise of a baby playing with balls on the floor, above my bedroom.
I am surprised this is still a problem in the 21st century.
Market forces don't work for hidden features like this, so why would it ever change?
This is why people want to live in detached houses - after years of psychological torture from living in cheaply built or badly designed flats.

The cold is really the buildings fault. It's hard to explain it you are used to northern European construction. It seems to be colder inside than out! It's quite a common and well talked about problem.
What is good: weather, people, interesting places to visit 30min-1hr away, food, etc. What you'd expect really.
Ok, go ahead with them?
The main problem I found was the housing stock is in pretty terrible shape. Flats have basically no insulation and often have bad problems with damp. No insulation means the flats are freezing in winter and you can hear the neighbors do everything.
While eating out is definitely significantly cheaper, many things are (much) more expensive than in London. Supermarkets, home internet, cell service (brutally expensive), utilities (I was paying 10x for utilities in winter compared to London, because of the complete lack of insulation - and Portugal has some of the highest electricity rates in Europe).
Overall I would not suggest moving to Lisbon if you are expecting an overall significantly lower cost of living than London. There are lots of other benefits though :).
