It has to have summer, that is, 3 months of heat, not summer like in the United Kingdom or other northern European countries that have 2 weeks.
I don’t mind a hard winter, I tolerate the cold. But summer is important.
Rent should not be too high.
I want to be from the European Union because I have the right to work in those countries.
That it has good salaries.
Work in Geneva and live in France (Frontalier). Housing is far from cheap, but much cheaper than Switzerland.
