We had a great stay at Ninni's!! Her flat is lovely, very well decorated and everything you need including a shower (which is not always the case when we looked at renting flat in Copenhagen). It's located in Norrebro, a very nice area with bars and restaurants, also very handy to visit the city (depending on how good a walker you are it's only 15-20min from Norreport). It was very easy to find, We met Ninni directly at the flat very easily. Highly recommend it!
