Depending on your ability to work remotely, I would make the "case" that you should consider Portugal . Lisbon and Porto are super popular with ["digital nomad"] remote workers who work for international companies so earn in USD but spend [much less] in Euros for a superb lifestyle. There's a reason @paddycosgrave moved Web Summit to Lisbon. It's one of the cheapest cities in Europe and [unlike Barcelona] everyone sp…
I understand skipping Porto and specially Lisbon as prices literally skyrocketed in last years. I also understand that Braga is maybe the cheapest relevant city in Portugal, but despite that I would pick Coimbra for the intellectual vibe.
[Sadly] while AirBnB has made it easier for "tourists" to visit the cities it has accelerated the [ridiculous] house-price inflation, especially in short-term apartment/room rentals often pricing "locals" out of the market completely.
Coimbra https://en.wikipedia.org/wiki/Coimbra is a lovely city. It was second on our list precisely for the "intellectual vibe" (as you say).
What "swayed" our decision toward Braga was:
+ Much Closer to the Porto international airport via Bus, Train or Uber/Taxi. So getting to London/Paris/Frankfurt/etc. is a lot easier.
+ More existing companies both tech and traditional e.g: Bosch & Primavera. So the MeetUps are more "practical".
+ Lower latency and generally faster Internet.
Our plan in Braga is to "recover" abandoned buildings (which are currently empty/unused) and renovate them into amazing places to live & work for "location independent creative/technology professionals".
We are morally against Landlords/investors who are simply buying up the stock of available "rental" property and jacking up the prices so locals can no longer afford them.
