Relocating to Brussels

Hi there, My family and I are relocating to Brussels in 6 mths time and I would appreciate if anyone has advice or info on families moving to Brussels. My family consists of husband and two children, daughter of 9 yrs and a son of 6yrs. We are an Irish family currently living in South Florida. Although we are moving nearer to home we have being living in America 8 yrs and have gotten used to life here. We are looking at St John's Int School and the British Int School. If someone could help on giving me any info. on these schools I would appreciate it. We are not sure as to which area we will live. My husband's job is located at the airport. Is Brussels a good family move??? Thx
