We stayed for 4 nights at Arne & Annette’s place and it worked out well for exploring Copenhagen. The metro stop is just a few minutes away and takes you to the city in minutes. Arne was very helpful with suggestions on how to get to the apartment from the airport - taxi was the quickest way and not that expensive. He couldn’t meet us, but was very responsive via email to any questions we had, and also provided his phone number in case we might need it.
The apartment is on the second floor, so take that into account if you have mobility issues. It is located over a some type of electronics store, and the building and the back-entrace to the apartment seem a little run down. The neighborhood nevertheless felt safe and quiet, despite partying across the street on Friday night. There is a convenient small grocery store a short walk away. There is also a little pizza place right across the street, yet we never tried them out.
The apartment itself was well equipped and had plenty of room for our family of four. The kitchen had everything you need for cooking and the living areas were comfortable with a large screen tv. It is not an upscale place, but certainly comfortable and within easy reach to the city.
