We enjoyed our stay at Karin's place. It is located in a quiet neighborhood, but within 5 to 10 min walking distance to the Hötorget metro station, which will get you to the Central Station and Gamla Stan within one or two stops. The metro stations were quite big, so take a few minutes to learn the exits so you can find your way underground. We bought a 72 hour SL access card, so we could use the convenient public transportations within the city to visit museums and Gamla Stan. There were also lots of good restaurants and grocery stories near Hötorget station, so do explore the area to see what's around there. Karin's place has all the essential items we needed like towels, toiletry, and cooking equipments. We were able to make breakfast before we headed out for the day, so we were able to save some money. We didn't get to meet Karin, but her team of hosts were very responsive.
