“我已经在巴黎住了6年，所以我很习惯这里的生活”翻译成英文

I have been living in Paris for 6 years,so I fit the life here very well.
个人觉得说话的人到这时还在巴黎，因为后面说的是习惯这里的生活，而不是习惯那里的生活，所以应该用have been living

I have lived in Paris for six years, so I am very used to living here.

I had already lived in Paris for 6 years, therefore I am familiar with here life very much

I have lived in paris for six years, so i already fit the this kind of life .
