""Rumor has it that J.K. Rowling’s inspiration to write Harry Potter has begun in Porto, particularly at this library. The well-known writer lived in Porto for 10 years working as an English teacher in the early 1990s and she used to drink a cup of coffee at the second floor of Lello’s bookstore. There are indeed great similarities between Lello’s bookstore staircase and the one described in Hogwarts." http://www.localporto.com/bookstore-world-porto-lello-irmao/"
