Living in Brussels
I lived in Brussels. I am an American and joined the American Club of Brussels. Anyone, of any nationality, can join. They were a great source of information on all aspects of living in Brussels. They also gave very good cocktail parties where I met many people who were able to give me assistance. Brussels is the European headquarters of many international companies so there is no shortage of English speakers. Whatever your interest you can find an English-speaking group.
The Bulletin is an English speaking magazine geared toward ex-pats with ads for apartment rentals. Some of the apartments in this magaizine are more expensive, but the landlords are used to dealing with English speakers and they can help you work around all of the weird rental laws. There is no shortage of rental housing.
There is an English-speaking Anglican church with a pub in the basement for "communing" with other members. Unfortunately I cannot remember its name. However, it is the only one so it would be easy to look up. I met several pilots there and they have great outings and social events that are not too religiously oriented.
I always say that Brussels is a great place to live, but you wouldn't want to visit there.
Just remember, their revered national monument is a little-boy-peeing fountain that they dress up for various holidays and their motto is...if you can't see the tower of the city hall then it is raining, if you can see it then it is going to rain!
