First before you come here make sure to rest a lot.

Vienna is the geographical center of Europe. Here are some responses from people who live in Austria.

I believe that they'd like Austria. There would be something to look forward to for all of them. Nature, Culture, Cuisine we got everything here especially in Vienna - Verena

Some nice sights the boys could visit. Plus, it’s save. - Chris

Austria itself is super beautiful but Vienna is still my top recommendation, the art galleries are so gorgeous, the food is yummy, we have fun and interesting sights... If I didn't live in Vienna it's the first city I would wanna visit - Karo
