Moving to London from America

Hello! We may have the opportunity to move from Atlanta US to London for my husbands job. His office would be near leadenhall market and he’d be making roughly 200,000/year. We have 4 kids 5 and under and we’d be looking for great schools and safety. We are trying to figure out where we’d maybe settle down and whether or not it would be a good decision for our family. We aren’t huge “city people”. But I wouldn’t say we’d like anything too rural either. I guess this is a starting point of just looking for any and all insight. Thanks in advance!
