My stay in Charlotte's apartment was simply perfect. She found and easy way to give me the keys even if she was not home (dropped them in a coffee on the corner of the street). When you arrive you have an helpful map of the city so you can enjoy the city as soon as you arrive even if you have planned nothing. Charlotte is very helpful, if you have any question you can ask her or her daughter and she/they will help you to find what you are looking for.
The apartment is clean and not so far from the city center of the beach (15mins each). The M2 metro drops you 5 mins by walk from the apartment so you can Reach and leave the city easily.
I recommend Charlotte's apartment and I know where to stay the next time I visit Denmark.
