We enjoyed our stay at Sofia's place very much. The kids (one and three) loved the children's room and the playground and beach which are just a few minutes away from the apartment. It is in a nice neighborhood with good connections to the city center. We decided (because of the kids) to use the Arlanda Airport Express (train) and the metro to travel from the Airport to Hornstull. It is a bit more pricey but also very convenient. The supermarket is just across the street and restaurants and foodtrucks are also close by. We did not have the opportunity to meet Sofia in person but she responded quickly to all our questions. Overall a great stay in a great place!
