Staying at Nicolaj's place was really great. It is perfectly situated, you can easily get to the city center (we would walk normally), to Christianshavn etc.
Communication was super easy, with super instructions on how to get from the airport to Nicolaj's place. The room and the bathroom were both clean and nice. The bed was very comfy and warm - which was really convenient since it was quite cold when we were in CPH. If a couple should happen to be, say, off-standard physically, the bed may be a bit too cozy.
Other than that: Nicolaj and Ray were really nice hosts, the area is beautiful and the best starting point to discover CPH. This AirBnB host is highly recommended!
