You will not stay alone. The Porto 1-Month Tourists community is already waiting.

Thirty days teaches the rhythms nobody puts in a guidebook: which cafe holds a table past ten, when the Boavista traffic actually clears, who to ask about extending a D7 visa without the paperwork nightmare. Most of this group is remote-working, long-holidaying, or quietly testing whether a month becomes a year.
Group vibe
Settled in, mildly evangelical about the city, allergic to the word tourist.
Example members. Real archetypes drawn from the people who already meet up here.
