Helle is a very nice and friendly host. She took us in with a last minute reservation, replied to our e-mails very quickly, she was very kind to wait for us coming from the airport to welcome us and was very flexible with check-in/check out.
She provided many useful information, left also some maps and infosheets, and even a bottle of wine and an orange juice for the kids were refridgerated for us when we arrived.
Helle's appartment is very nice, stylish, comfortable and clean. It is in a perfect location, close to the city centre, very accessible to all of the sites, just a short walk from the metro and the bike station - we went everywhere by bike during our stay in Copenhagen:-)
Highly recommend Helle's apartment!
