Erik's place is very nice, modern and cozy. It's 6 minutes walk to the subway and close to Liliholmen area, Gamla Stan and Central Station.
He and his daughter are friendly, kind and very generous. They invited me to their boat once for dinner and shared with me dessert and some food. That was a plus.
They were on vacation some weeks of the time I stayed there so that was fine for me.
If you are a coffee lover there's a coffee shop one block away from the apartment.
An extra star for the swimming pool that is available during summer time.
For these reasons, I can highly recommend you to stay at this place.
