Why do you like Berlin?
I live 4 hours from that city and I consider it to be one of the best in Europe. I'm particularly interested why others like it because I still have it on my list of life targets :)
What ended up driving us away was the red tape running a startup in Germany and dealing with taxes, etc. Normally we wouldn't let this deter us, but we had a shortlist of other places we liked just as much.
