Portugal as a country may feel nice. Someone I know was in Portugal for sometime and then he got into their national water polo team so they are definitely a welcoming bunch.
Also I met a couple from Portugal on train in India and they felt very sweet ppl to talk to.
On a side note: all foreign nationals that I have talked to, all have been equally sweet to me. And there are like 25 nationalities that I have talked to. I don't recall anyone being not sweet.
