We were traveling in Copenhagen for work and the central location was perfect. The Rosenborg is spacious, super clean, and the communication was very prompt.
We had a little issue with the main light switch, that mysteriously fixed itself when someone came to look at the problem, and they were there within 15-20 minutes of me sending a message.
It's a very pretty space that's big enough to be comfortable for traveling with a coworker. The kitchen is set up for making simple meals which would have been very convenient if traveling with a small family. They also provide complimentary washers and driers in the basement which is pretty important when you're traveling for 10 days with a carry-on!
I would return!
