We had a very pleasant stay at Jens place while visiting Copenhagen for a long weekend. The flat is very huge and fits a high amount of guests very well. It is located in a central location: Main city and shopping centre, Nyhavn harbour and the Rosenborg park are only a few steps.
Our host Jens Rasmus was great. He is always there when you should have any questions and made our stay very comfortable.
I strongly recommend this place for staying in København for 4 people.
