I know at one point, Finfou was teaching in Stockholm, or very close by at least. I am not sure if that is still the case, but he does speak a little English if you can't speak Portuguese, so I would message him on Facebook. The last time I spoke with him, it took a little time for him to get back to me, so be patient. Jackson Souza was also teaching in Sweden as of 2015, but I am almost sure he is located in the UK now.
I haven't been to Sweden in a long time, but I remember it being pretty easy to get around, and the train was easy to use (I traveled from Rocksta to Stockholm almost daily) so you may have a wider range to check out if you are willing.
