We really enjoyed our stay in Stockholm. Olof gave us all indications in order to reach the flat at our arrival (8:00PM). Consider 1h to reach the apartment from Arlamda airport (20min with Arlanda Express and 40min by feet). Furthermore the flat is not so far from the center that allowed us to visit many places and typical spots of Swedish live. The apartment is quite convenient for cooking in cases where we don't want to diner at restaurants.
The apartment get a neated design and rooms are cleaned.
We fully recommend that place to visit the city.
