Nina's place is amazing.
First, it's a really cool flat with a great bedroom, kitchen and living room.
Secondly, it's in a great location for exploring Copenhagen. There's a bakery that does amazing pastries across the road and there's a supermarket 2 minutes away for everything you need.
The apartment is right next to the water so you can walk along an awesome scenic route with some great views. You can walk easily to many of Copenhagen's best places such as Vesterbro (the cool area) to get some food, Christianshavn, Nyhavn; to see the sites, The Meat Packing District; to get some drinks in the evening. And if you don't feel like walking, the Metro station is 5 minutes from the apartment and it's so easy and cheap to use to get to anywhere that's further out.
Nina was also very helpful during our stay, with quick responses; she also met us as we arrived and gave us tips on where to go on our first night and how to get there.
Overall, if you're looking at getting this apartment for a stay in Copenhagen, just get it, it'll make everything so much simpler and better for you :)
