My husband and I spent 4 nights here. In some respects, it was great. The location was very convenient, steps away from the Rosenborg gardens and within walking distance of everything we wanted to do in Copenhagen. Frederik helpfully provided check-in instructions and answered our questions about public transit from the airport. We found muesli and ground coffee in the kitchen, which made for a nice breakfast every morning after we picked up yogurt and milk from a nearby Aldi.
Some aspects of our stay could have been better, though. The soap dispensers in both the kitchen and the bathroom were almost empty when we arrived. The coffee maker was tiny, so I had to make 3 pots every morning to fill one cup of coffee. There was a fair amount of street noise at night, mainly from cars driving by. When we shut the windows to keep the noise out, it got hot and stuffy inside; a fan would have been helpful. This is particularly true because it seems like in Denmark, people don’t use top sheets. The only covering on the bed is a heavy duvet.
All in all, with a few minor improvements, I would recommend this apartment.
