We stayed at Helles beautiful apartment for three nights and everything was perfectly fine. The apartment itself is really big (dining room, living room, 2 bedrooms with 2 large beds, kitchen, bathroom) and she simply has a great taste in interior design!
The apartment is on the 4th floor without an elevator, so maybe it could be difficult if you travel with a wheelchair or buggy. The neighbourhood is really nice. It's just a short walk from the old town and very close to Nørrebro, where you can find a lot of restaurants and bars.
Helle was really welcoming. She gave us a list of tips for the city and even bought us a bottle of wine as a welcome gift. I would definitely recommend staying at her place, we really felt at home there.
