Psy horror I suppose.I don't know how old really.I just remember the strange hotel with couple of rooms and guests were terrified by a strange things that happens in the hotel,like ceiling in the room is going down.I think there was an interesting housekeeper maybe some grandma and they all having dinner on the same samop table... ahhh I was young.
Thanks anyway!

While its not really a horror movie, this sounds a lot like Murder by Death (1976)
