Hi Ron, my stay in Germany is coming to an end, after 6 years here in Munich. Can recommend being based here. Have a look at Munich.de website (also try "Toytown" for the expat view).
The good things:
1. Slick transport to the airport (45 mins from City centre to MUC), cool integrated transport system (S-bahn, U-bahn, Tram, Bus all usable with the same ticket and many ticket options)
2. MUC is expanding rapidly - 3rd runway coming
3. Beautiful, clean (generally) and safe city with a large expat community
4. Great beer, food, football, skiing, culture, nightlife and shopping
The not so good:
1. Rents expensive
2. German tax and social security expensive
3. Fuel expensive (on a par with UK)
4. Munich city centre about to go "Green" with heavy restrictions on vehicles corresponding to emission levels - some will not be allowed into the centre at all
PM me if you would like any further info - by the way, I have no knowledge of schools or kid stuff.
