Where to stay
I would highly recommend staying near Tivoli Gardens as its near the centre of town and shops, tourist areas, etc are easily accessible. We stayed at Nyhavn, which was nice but had to take taxis everywhere.
If you are like me and hate using public transport in foreign countries uber it everywhere!
The uber cars turn up within 5 min and drivers tend to be more helpful than the taxi drivers who won't even help you with your luggage!
Also walking around the city is quite pleasant and scenic.
People are friendly but not st the airport! They seem to go out of their way there to be difficult and rude.
