Heidi is a very welcoming host. I stayed at her place for 12 nights, and found it clean, comfortable, and convenient. It is quite near to Østerport train station as well as bus routes into the city, so transport is not a problem. I didn't meet Heidi in person, but she replied promptly to messages, and her sister was also available to help with any urgent problems. Would certainly recommend this listing to other travellers.
