I recently left Alexandria after living there for 6 years. I'll be honest it was not my kinda of place but I've no regrets and there's parts I did enjoy. Smouha is an okay area but it also depend on where in Alexandria your be working. Alex's gets heavy traffic, especially in the times you would be on the move!
I've not been to the Portuguese Club in sometimes but know its prol your best bet when it comes to meeting foreigners other than from your work place.
I never really felt unsafe wondering around Alexandria but like anywhere it's common sense such as remaining in well lit populated areas. Same as anywhere. There is obviously areas' in Alex's where your more likely to get stared at than others. Smouha one of the safer areas as some others too.
Language wise I never did learn full blown arabic just enough to survive. Like key words. Yes, No, Thanks etc etc.
