I love Porto, not sure if I love it more than Lisbon or not. When did you visit Porto? When my daughter and I visited the Lello Bookshop in January 2015, we walked straight in. There may have been one or two other people inside but we sat down and had a ( dreadful) coffee at the little cafe. This was obviously before its rise to fame as the J.K. Rowling inspiration. Some of the stained glass was broken and it was looking a little worse for wear. I loved it though!
