I visited Manor House station in July 2019. There is a long elevator to exit or enter the platforms to the ticket hall, and then a lot of stairs to get from the ticket hall to the various entrances.
All the London railway stations :
Underground lines : Piccadilly
Manor House station
Manor House elevator
Manor House - Seven Sisters road exit stairs
Accessibility friendly : Manor House is not accessible to wheelchair users due to escalators between the platform and street level.
