Multiple cities. At least Ramstein and Spangdahlem are really big and could count as a small city. That’s why I said there is still a good infrastructure even after a lot of US soldiers were sent home and bases got closed in the last few years.

And also there is still a big US infrastructure at hand with all the bases.

As others said Switzerland. It’s beautiful and all but really expensive. It really took away a big part of fun when I went there. But not only that, I thought the swiss people seemed sometimes kinda "rude"or maybe a better word for it “cold” and a little annoyed if it came to tourists. I get it, it’s a small county and a lot of people are visiting each year, but it still wasn’t fun for me to be there and I wouldn’t recommend it to anyone to go there.

And North France near the German border like Strasbourg. The city and the region is beautiful as well, but the people are often like the cliché everybody knows and that sucks if you’re a tourist. But the south of France like Marseille and the Provence is always worth a visit. The people are chill, enjoying life in the typical mediterranean way and are often friendlier (and often speak English at least in the bigger cities/tourist areas).
