Lovely well appointed unit. It's 3rd storey but there is a small lift (you need to climb about 3 stairs to access the lift). Kitchen is very well appointed - lots of cooking utensils, pots etc - only thing missing is a toaster ! (Danes don't eat toast - we grilled it in the oven). Siemens Oven and Induction hotplates are great. Probably the best appointed kitchen I've stayed in - it even had cling wrap and plastic containers for left overs. No blinds on living areas (that's fine) but quite good blinds on bedrooms - the sun went down very late and rose early in July.
5C bus stops outside the building - that takes you straight to the central train station or Norreport in one direction - or the other direction it goes to the aquarium and the airport. We caught it to the airport (make sure you have cash if catching a bus) - it was very handy, stopped directly infront of the airport and we saved dragging bags through a train station. A couple of blocks away there are other buses (1A, 2A, 9A etc) which we used to access the east side of the city - ie Christianborg Palace, Nyhaven, Amalienborg, Shopping district).
The only slight negative - there are no big supermarkets nearby. There is a small corner store about 2 blocks away which we used to begin with and had most things. We then discovered it was easier to buy something if needed on our way home (supermarkets are in the Central train station and Norreport) and we could catch the 5C bus straight back to the front of the unit. We'd purchased the Copenhagen card which made jumping on and off buses very easy. Highly recommended and I'd happily stay here again.
