I really enjoyed my stay at Ellen's place. The apartment is cozy and big enough for 1-2 persons and you get everywhere really fast by bike. While the apartment is definitely old, all appliances work flawlessly and it gives the apartment a nice flair. There are several supermarkets nearby and it's just a short walk to Gammel Kongevej where you can find several great restaurants. The apartment also has a bike rack in the courtyard where you can safely park your bike.
The only main critique I would have to make is the check-in. While it said 12:00 in the booking Ellen said she could only let us in at 18:00 and we had to stash our luggage in a different location in the meantime. She only offered to give us the keys to the place a day early for an increased price of around 50€, which I refused. In the future, don't put that early of a check-in if you know you can't make it.
