Me, my husband, our 18 months old son and my mother in law stayed in Karolines flat for 5 days and it was really gorcious. The flat was clean and spacious and located close to a supermarket and a metro station only some stops away from Central station.
It is a perfect flat to stay with small childs, there were plenty of lovely toys and everything was adapted for necessities with children (high chair, child-proof locked plug sockets, stepladder for the bathroom...).
Karolines daughter welcomed us very friendly and was always very helpful in case of questions. She even left a "starter package" for lunch for us (bred, juice...). Would definitely and maybe will come back to this place! Thanks a lot!
