As rica I also was born in Porto Alegre and lived my entire life here. Ever since I started playing poker for a living I have traveled all around the world, I've been to many many places and for some reason I always find the need to come back to Porto Alegre. We do have problems with urban violence I can't lie to you, but if you avoid certain regions of the city your odds of being a victim of any kind of crime will decrease drastically.
All the main aspects of the city were pretty much covered by what rica said, it's in fact a very cheap, clean and resourceful place to live. You always hear about foreigners saying that people in Brazil are very receptive and over all nice when in fact when you go to cities that have a big tourist traffic you will find rudeness and "dirty" people trying to get away to little schemes, but in Porto Alegre people have a VERY VERY different way of approaching things, I'm trying not to sound snob but in PA we have a way higher level of education than the rest of the country and that reflects in the way things work around here, for example the cab drivers are MUCH MUCH nicer than in the rest of the country, what I mean by that is that here we have a more American approach sorta speak, things are "more official" than in the rest of Brazil where in many situations people tend to stretch a few rules and let some things fly in order to get something done (bribes, abuse of power from the police and so on.). Though I think people from PA, are just nicer than average by default I think that would look suspicious coming from me that's why I tried to explain as much as I could but it feels a little confusing now that I'm reading it again, I hope you guys can get the message from it.
Bottom line: PA>Brazil, don't get me wrong Brazil is great but I just feel that we are ahead in terms of quality of life than the rest of the country and I really hope they'd catch up with us.
One more thing, if you are foreign and want to come to Porto Alegre you might be in luck, my mom works exactly with this type of thing she actually makes arrangements for companies who need to bring executives from outside of the country, she will take care of housing (hosekeeper or maid if wanted.), car (driver if wanted), over all guidance to the city, information about how to get a permission for your visa (extend it or make it permanent if possible.), if you guys want more information you can e-mail her at
amarilisdn@gmail.com or you can add me in the msn or google talk using
giovanni.davids@gmail.com for both programs, I know everything about the logistics of my mom's arrangements so I'd be able to clear any doubts you might have about anything. Just to save some of your time, there is not a fixed price for anything it's all according to what's arranged for the client so if any of you want prices you'll have to provide a list of everything you'd like to get here and she'd make a detailed list of how much each thing would cost with her fee included.
