We had trouble accessing the apartment building as the key did not match the locks, which meant the only way we could get into the building was to buzz/call other apartments and ask them to let us in.
Fortunately there was a group of us and Copenhagen is a safe city, but I can’t imagine how frightening this would have been for a solo traveller to be stuck outside, sometimes past midnight, without access. When we spoke to the host about this there wasn’t a real solution, they just told us to carry on doing what we were doing (buzzing apartments).
The water pressure in the shower also needs a lot of work as it’s very low.
I also wouldn’t recommend this apartment to anybody who needs help going up stairs, as it’s at the top of the building and there is no elevator.
Otherwise, this apartment is in a very good location and has everything you need.
