Rui's house is a wonderland of books, It's tiny but lovely, just like the pictures he posted on Airbnb. the house is in alfama which is the most time- honored and attractive district in Lisbon, very safe and peaceful. It's 10-15 mins walk from metro which can take you around the city or other town like Cintra. Rui is a really good guy, even we only met for about one hour, I already feel like his friend. In a word, It's an interesting place to stay, and a great place to get you started to know about Lisbon.
