My wife and I stayed here with my two children under 10 for 5 nights. Overall we very much enjoyed our stay at Marina's place in Copenhagen, but there are definitely a few things that could be improved about the place. TLDR: This place is great if you're traveling on a budget and are not picky.
Marina was wonderful, everything you could every want from a host. The bed was comfy, the apartment was clean and warm.
The shower was unfortunately awful. You couldn't use it without the lining sticking to you while also getting water all over. There were no shelves in the bathroom for toiletries, etc.
The kitchen was lacking a few staples, but had enough to cook a, meal with some supplemental buying.
Neighborhood was safe with plenty of walkable options.
If you're traveling on a budget and are an easy-going traveler, this would be a great option. But I'm gonna have nightmares about that shower, lol
