We really liked our stay here (as a family of four). Very family friendly apartment in a quiet neighborhood. It only takes a 10min walk plus 10min train ride the center of Stockholm.
Parking was easily possible for 6€/day at Årsta Sjukhus just a few meters away from the flat.
Emma prepared everything really carefully before we arrived and was also super-fast in reacting to any question we had.
In total, I fully recommend this place.
