Isabella’s apartment is a good one for a single or a couple with two rooms (one bedroom and one kitchen/living room) and a typical small danish bathroom on the fourth floor, without an elevator. It is located close-by a lot of restaurants, sightseeing spots and supermarkets.
We spent there four days and rented next to the Kvickly supermarket (very well equipped) two bikes, what I always really recommend in CPH because of great bike lanes. The apartment had everything what you need and Isabella is a good host.
