Amazing apartment. We loved our stay, as the space has so much charm. Sigurd was very welcoming and accommodated our unexpectedly very late arrival (KLM overbooked and bumped us).
Small drawback: the noise from party people on the street was a bit loud late at night. Very quiet during the day. We still loved our stay, because it was such a great space and in a good location. Honestly, the apartment is pure magic.
I'd recommend it, and happily stay again.
