Very professional staff. Repairs when needed are very quick. Building is kept clean and safe, pest free. Seems like they choose tenants carefully, everyone is quiet and civil. Two small gyms in the complex are free of charge and very useful, don't need more. If you need more, Chelsea Centro is near several full service gyms. Also close to the 1, E, C trains and not far from F, M, R. There is a large 14th floor outdoor common area which is wonderful in good weather. They keep the corridors and laundry area well cooled in summer and well heated in winter - not all landlords do that. If and when I move, I will first seek to move to another building by TF Cornerstone because I know they are very professional and reliable.
