I had a wonderful time in Copenhagen! Pi was very welcoming, kind, and helpful. Pi sent me a practical map with the route to her place on it beforehand, she helped me to find the Tourist Information and contacted them when I got there, she helped me to figure out the train schedule, and she even offered to drop me off at the station on my way to the airport. It's a 10-minute walk to Østerport Station and approximately a 30-minute walk to the center of Copenhagen, which is perfectly doable. The room was just as described in the advert; it was clean, cosy, and beautifully decorated. The bed was very comfortable. I would definitely recommend staying at Pi's place!
