Hey! I was born and raised in Vienna and live here now.I spent 5 months living in NYC in 2022. I would compare Williamsburg in Brooklyn to a combination of the 6th (Mariahilf) and 7th (Neubau) districts of Vienna. Lots of hipsters and young creatives. Nice little restaurants, bars and shops. A very friendly albeit damn-i'm-cool vibe. Park Slope would be comparable to Vienna's 2nd district (Leopoldstadt) which is the home of the famous Augarten (similar vibe to Prospect Park). Lot's of young couples with their babies. Also the wonderful Karmeliter market. An understated atmosphere without being boring.I lived down in Bed-Stuy while I was in New York. The 16th district (Ottakring) feels like a good counterpart to that. Very diverse with lots of ethnic food shops and a great market (Brunnenmarkt). Like Bed-Stuy, students as well as young families have recognized the charming neighborhood and appreciate the lower living costs. I foresee jentrification in both places. I hope i'm wrong.That's all i've got for now. I wish you all the best in your research and i'm delighted by your interest in my hometown :)
