We had a great time in Copenhagen staying with Pia. Her apartment is a 5 min walk from the train station. You can walk to many restaurants and cafes from her place (we liked going to Warpigs for local beer and American style BBQ!) Pia is super nice and quiet. A lot of people complained about smoking in their reviews. My boyfriend and I are very sensitive to smoke, but we didnt even notice it during our stay. She kept the door to her part of the apartment closed most of the time we were there.
