We had a great stay at Den's place in Copenhagen.
He was flexible with check-in. we were able to drop our bags while it was being cleaned & then check in early.
The location is amazing, but incredibly noisy. We were there over the weekend, and during the time of Christmas Markets, so maybe an extra rowdy time, but both nights of our stay we were woken up, and then up until 5am due to the noise.
Otherwise, it was a great stay.
