We stayed with 4 people in Ibs accommodation and overall had a very nice time in Copenhagen. Ib messaged us before that he won't be in town for the time of our stay but the self-check-in and check-out worked flawlessly and everything was already prepared for us. The apartment is very well located and it is only a short ride by the metro to the city center. The only minor downsides were that the kitchen was not completely clean and the sofa-bed in the living room was a little bit small for two people. We did not use the bed in the annex as it was still pretty cold and there was no heating/electricity. All in all, we had a nice time and would recommend staying with Ib.
