Lovely. Great weather all year around and close to skiing, hiking, biking, beaching. Also very cheap compared to other big EU cities. Great place to dine out, and drink... Cons: tourists in specific areas, and there are constantly tons of cars on the streets which creates an awful air quality, especially during winter. Not something you would notice as a weekend tourist. Also lacks pleasant parks in the center (there are a few though). From a professional point of view, the city stil lacks the talent & creative momentum of other vibrant EU cities, but it's getting there quite quickly.
Also a great city to discover the rest of Europe since there are several cheap quick flights daily, and the airport is very nice and close to the city center.
