This AirBNB in Copenhagen is perfect for a family of four. My teenage kids and I stayed here and loved its location and the ample space inside the unit. Although it is located on a busy street, it was quiet at night. The blackout shades also worked well. The hosts communicated so well, day and night, 24-7. I noticed that when I would email them from home in California that they would reply right away even it was the middle of the night in Copenhagen. The unit has a handy iPad with an app specially designed for the guests. Our unit was on the 3rd floor and had great sunlight. The lift made it easy to go up and down. The building's security was excellent with unique key codes for entry into the building, the atrium and then into your actual unit. We were steps away from the tourist zone and literally a block from Tivoli. If you want to be right in the middle of the action, then this is the place for you.
A few notes to be aware of. There is only one bathroom, which I knew going in, but it was tight and for four people in the same family, ok, but it would not be a space I'd consider if traveling with another couple as you would be all over each other in the bathroom. My family found the beds comfortable but the pillows uncomfortable. I suggested to the owners that they invest in new pillows that aren't so flat and soft. Finally, little things like tissue and paper towels are not provided. Normally, I would expect an apartment to have those things especially given what we paid for this unit.
All in all, a good rental in a great location in a fabulous city. Have fun.
