I stayed at Vivians place for just over 2 months this winter and it was a wonderful "Upper West Side" experience! You are right next to Riverside Park with great walking/ running trail options along the Hudson river! The neighbourhood is home to Columbia University, the Manhattan School of Music, Union Theological Seminary and tons of great historical architecture. Right below the flat is Pisticci restaurant which became one of my favourite all time restaurants in the world! It was like a home away from home gastronomic wonder! I would stay here again in a flash!
