Nice party or museum location for all ages. Local can be both friendly and rude at times. Best to not let the few bad apples affect your trip. People from all over the World. Alot of tourists. Try and venture further away from the town and experience the true city if you have time.
Insider Tip:Watch out for the bicycles! Know your way around the town (google maps). Don't buy drugs in the street! Use the trams to get around instead of walking everywhere. Wear comfortable shoes! Say hello/ good morning before you buy or ask for something. The locals will remind you of this which can make for an awkward situation. Smile and enjoy yourself!
