Stina's house is located in a residential villa area in Knivsta, only 15min car ride from Arlanda airport with walking distance from downtown Knivsta where you can find super markets, pizzeria's, alcohol store, Train station etc.
However, even though it might be walking distance to the train station I would still recommend anyone staying in Stina's house to have access to a car. Knivsta is a small town in between Stockholm and Uppsala, and to get the most out of the visit, a car is necessary.
The house is modern and clean with cosy furnitures well suited for a family. Appliances such as Laundry and Dish Washer exists.
We stayed 6 adults in the house without issues. 2 adults in masted bedroom and 2 in each of the children bedrooms. We were a little bit worried that the children bedrooms might contain small beds, but don't worry. It worked out great even for adults.
