This is an amazing location and Per offers some very helpful advise. I would recommend for 2 maybe 3 people only.
The accommodation was lovely and had some great personal touches such as lighting.
We would recommend anyone wanting to use the TV to bring an Amazon fire stick as there are TV issues.
The one thing I would flag (which we are used to) are spiders are often in the apartment due to the heat and being by the water during summer.
Overall I would recommend for somewhere outside of Copenhagen central with easy access via bike, boat or walking (40 mins).
