Been living here for 6-months. Not the most sociable place, people are a bit avoidant. Apparently a 'Northern' thing. On a good note not very windy.
Food is pretty cheap as In Germany in general. Summers are quite nice to spend around some lakes and river beaches.
Flight connections are amazing. Also airport functions even with staff shortages, not overcrowded.
You can get around without German language that's for sure. On a very basic level.
But having a conversation or dealing with paperwork outside of city-center can be tricky.
Crime is very low. There is a large party area. Some pretty fun clubs.
Probably for a nomad I would not recommend. A bit snobby/cold.
But for a short-term work-stop is okay.
Spacious and calm overall.
Lived in Hamburg for 12 years. Nice place, but on the brink on turning in a bad direction since around spring 2020. Freedom of speech and freedom are in decline.
