Hello, I've found this explanation in a book, I hope you find it useful! Present Perfect Simple & Present Perfect Continuous We use the Present Perfect Simple to talk about something we have done or achieved, or an action that is complete. It is also used to say how many times something happened. e.g. We have watched that documentary five times in the last month. We use the Present Perfect Continuous to talk about how long something has been happening. It is not important whether or not it has finished. e.g.The tropical storm has been going on for days.

I think it is also about context and what you want to emphasize. The first is the present perfect tense which usually emphasises the result. The second - 'I have been living here' is the present perfect continuous - where you are interested in the process as well as the result. Subtle differences - but both would be OK in most cases. Hope that helps?

Thank you for the link!

This previous italki answer was pretty good. It explains that the first sentence has a more finality to it. https://www.italki.com/question/104535?hl=en-us

I think the second one is just the emphatic form of the first. The first is definitely more common.
