We were lucky to stay at Christel's place with our two kids (6 and 4 year old). They loved to play with the toys. Christel is very responsive and was able to help us with all out needs.
A cosy place for 4 people. The place is comfortable and has everything that a person might need for a short sting in Copenhagen.
It was very clean, beds were comfortable and kitchen had everything you need to cook a meal.
What you do have to be aware of: it is 3rd (or 4th if you consider ground floor as 1st) floor walk up. No lift. Many stairs if you have heavy suitcases or your legs are not too strong. There is no washing machine available - public laundry facility is around the corner. And lastly - there is really no bath (just a shower attachment above the toilet seat).
However, our stay was great and we recommend this place for others.
