Marianna is a very nice host and the boat is lovingly furnished.
Although I do not sleep well on hard mattresses, I was able to sleep extremely well in the bed.
The harbor where the boat is located, is not very nice. However, there is the possibility for beautiful walks to the next, great neighborhoods or to the center (approx. 4.5km).
On my next stay in Copenhagen I will ask Marianna whether her boat is available and recommend it to others.
One more thing: At the weekend, a party bus drives through the area - until at least 22.00h loud honking, later at least with loud music. Annoying, did not really bother us.
