I don't think that Rui needs my positive review here since he has already enough of them... yet I would like to write publicly that Rui's flat was very special to me. I spent quite a long time studying his books (in different languages about different subjects) and I owe him some goods hints about Portuguese literature. It was nice to get them at breakfast, chatting with Rui at the kitchen window.
And Graça, the neighbourhood he lives in, is a lovely place to explore.
