Nina's place is great. It is close to the city centre, about a 10-15 minutes walk. It is also 5 minutes away from the bar scene at St. Hans torv. There are restaurants, grocery store and a pharmacy in a 2 minutes proximity.
The apartment is lovely and spacious. Spacious bathrooms are not a given in Copenhagen. The kitchen has a balcony towards the city. Watching the sunrise while eating breakfast was amazing.
I will definitely try to book Nina's place again next time I come to Copenhagen!
