Do you speak Portuguese? Are you interested in learning it? I don't know how big a role it plays in making connections and friends in Portugal, and how important those are to you. It may be also more difficult to find English (or Turkish!) speakers in smaller towns compared to big cities.
How stable is the remote role? Are you more likely to be laid off (or the company to cease operations) than turmoil in Turkey? Obviously this is also very subjective speculation, but since you don't mention it, how does it figure into your plans? How well will you be able to find other similar work in Portugal? (Or elsewhere, I would assume your relocation will offer freedom of employment across EU.)
