Traditionally, apartment prices are considered to relate to the apartment characteristics and its location. We had a hypothesis that accessibility of a neighbourhood perhaps is even more important than its location. So we did a pilot study in Helsinki region to check that.
First we define static and dynamic points of interest in the city. Static points of interest are supposed to capture community centers. We find them by locating H&M stores in Helsinki region. Dynamic points of interest are supposed to capture where people go at different times of day. We find those centers by clustering FourSquare check-ins.
