Camilla's place is conveniently located between Nyhavn and Christiania near the canal. St Saviour's Church is only a couple blocks away as well (I recommend climbing the church tower). The neighborhood is quiet and feels relatively safe. The Metro and buses all are within a short walk of the flat which makes getting around a lot easier. We didn't meet Camilla but she made sure that we were able to check-in and out without any trouble.
The flat is charming on the inside with plenty of windows for natural light. The rooms were thoughtfully decorated with paintings and trinkets making them feel cozy. The bathroom is small, but clean and useable. The shower water temperature doesn't get very hot, but is warm enough for a relaxing shower. The bed is clean and comfortable. The towels were a bit small and rough (probably due to hard water). The flat is on the 4th floor (that's the 5th floor for 'Americans'). Note that there is no lift (for those that may have difficulty with stairs).
If you are looking for small and boutique breakfast place nearby, "Sweet Treat" ( https://www.yelp.com/biz/sweet-treat-k%C3%B8benhavn-k ) has a wonderful oatmeal with lots of fresh fruit in it. Their croissants are lovely too.
Overall I would recommend Camilla's place and would certainly consider staying there again.
