Mette was a great host. This was my first trip using airbnb and it was everything I wanted it to be. Great value in an authentic, real setting to experience the culture, clean, uncomplicated and she let me just get on. The location is perfect meaning you don't have to really use public transport (as long as you don't mind walking).
This is my first trip travelling alone abroad and with that I admit I struggled finding the place even though it's straight forward! When you get off the train climb up the stairs which are enclosed as opposed to the open air ones. Then you cross the street onto Oster Voldgade (towards all the lovely orangey buildings). Turn left onto Kroprinsessegade. The street is about 5 streets down on the right and about five houses down on the right again.
There is a little convenience store called Fotex foods nearby. Just turn left when you come out of the house. Right at the end of the road. Follow that road until you go past the Italian food place and the store is on the left hand side. (You can't see it until you pass the Italian food place).
Just to help you get your bearings if you go past Fotex foods you will come to Rosenberg palace gardens on the right hand side.
I used a Copenhagen card when I was there which I bought online before my trip. It cost £80 approximately. This covers all your travel both bus and train and entry into most of the attractions (all of the ones I wanted to go to anyway). You also get discounts on several restaurants but I didn't use this.
Hope this helps anyone!
