I live in Graz, Austria. We also get snow for a short while in the winter (see my post with photos here in case you're interested: https://steemit.com/travel/@victoria-kelly/temperatures-in-graz) but the rest of the year it's pretty warm. Even above 35C in the summer! The location means that it's more like a Mediterranean country.
On the other hand, you're lucky because Berlin is a wonderful city. I was actually thinking about moving there at one point, but now I have a boyfriend in Graz, so I guess I'm staying here for the moment. :)
Oh it sounds nice, maybe I will visit someday <3 And yeah there are just so many perks of living in Berlin despite the shitty weather. It is the least judgy and the most free city ever. You can dress up how you like, be who you are, no fucks are given ever.
