We were very happy to stay at Gertrud's apartment and would love to come back another time. The apartment is perfectly situated at Christianshavn with incredibly easy access to the inner city.
The kitchen was well-equipped and we found everything we needed in the bathroom. Gertrud herself was very accommodating and easy to get in contact with. I would recommend this apartment to anyone wishing to enjoy a few days in Copenhagen.
Overall, we felt very much at home and were pleasantly surprised by how good and "hyggelig" the apartment is compared to the (otherwise nice) pictures.
