I was in town for 5 days to attend a conference at Bella Center. The location was ideal, as it is right next to the Metro station - literally a 1 minute walk. I got a Metro pass for the week and was able to go back and forth between the airport, the conference center, restaurants, tourist attractions and this apartment really easily. It beat waiting in line for an hour at the end of day at the conference plus I got to stay in the heart of Copenhagen, rather than in the middle of nowhere which is where Bella Center is.
Sisse was a great host. She checked in on me from time to time and also recommended place to go and explore. She even made a reservation for me at a hard to get into restaurant in town and I had one of my most memorable dining experiences in Europe that night.
The apartment is very clean and quiet with good security. It's been recently remodeled so everything is very new.
