Rosenborg Apartments is in a great location - less than five minute walk from the Metro and a 15-20 minute walk to everything you want to see in Copenhagen.
The apartment was great. Very spacious (other than the third bedroom that only fit a bed). New and fully stocked kitchen and nice bathroom with a great shower. Very clean and comfortable.
Rosenborg is incredibly responsive 24/7 as they advertise - I always got a response within 10 minutes, and they were helpful with recommendations.
The reason I can't give this apartment five stars is the noise. The apartments are on the ground floor and, especially for the bedroom in the front of the building it was very noisy in the mornings, with deliveries and garbage pick up on a cobblestone street, and at 8am the church across the street (which is just beautiful) peeled its bells for five minutes, and whenever the large automatic building door closed with a bang.
Overall, a really great experience and really great value.
