The apartment is all you need for your Stay in Copenhagen the location could not be better you do not need to pay for any transportation while staying there most sights are within walking distance (provided that you are fit)
You are approximately 100 m away from the walking Street about 1km away from the metro the canal boat tours 1 km from Tivoli
There is a cheap supermarket 600m away which really makes a expensive city affordable
Thanks Elio for a awesome time
