The booking was easy; and the getting there was easy-ish - took the metro to Amagerbro for a few DKKs...but the taxi not so easy - so get the Taxa app.
The keys handover was easy; and the apartment was great! Clean, tidy and everything I needed with wifi. Another great app is iTranslate to make sure you're using laundry wash or not.
Close to grocery store - which was open late on Sunday...for the milk!
My first stay in Copenhagen was very much nicer being in a smart apartment near to restaurants, parks and not far from the city.
