I was only there for a day, and it was March, so I didnt get to entirely explore the town, and certainly am no expert on Nerja. That said, it was by far the most touristy of anywhere in Andalucia, or spain for that matter that I went during my semester in Granada. I think there are a lot of English people living there and the influence is notable. I saw many many English language newspapers, and shops that catered to that group. Heard lots of English. That said, it was a cute little town and beatufiful beaches.
