Ronni's place was the perfect place for me to stay for my conference, which was also at Nordhavn. It's a beautiful new building that was very clean, comfortable, with great Danish design going on.
Checking in and out was very easy, and Ronni was very communicative. Though it takes about 30 minutes to get to the city center, I didn't find this to be a problem, and enjoyed staying in this quiet part of town. Within 10-15 minutes' walking distance were some nice restaurants, and a super market is just a minute from the flat.
I recommend this place whole heartedly!
