This was our first time in Stockholm, and the location could not have been better. William's flat is really right in the middle of the old town, walking distance (or a short ferry or train ride) to all the sights on our itinerary. The apartment has all modern amenities with nice old-world touches (high-ceilings, spiral staircase). Our group was a multi-generation family of seven people; William was thoughtful in checking ahead of time about the sleeping arrangements (number and size of beds per room) and made sure we were well accomodated.
