She's basically at the peak of happiness, isn't she?
Literal
She [topic-は] happiness 's peak [the-way-to-put-it-ってところ] is [right?-ね].
~ってところ(だ) is a casual, conversational frame meaning 'roughly, you could say, that's about the situation.' Built from quotative って + ところ ('place, point, situation'), it characterizes a state in approximate terms — handy for summarizing or evaluating. Sentence-final ね seeks agreement, soft and chatty. Together the sentence reads as a friendly assessment from a third-party observer. Casual って is the spoken form of the quotative と and is heavily used in dialogue.
