Elsa and Rui's place is one of the best Airbnb's I've stayed in. They were very communicative and offered to pick me up from the airport. I didn't get to meet them, but their friend Fernando picked me up promptly and gave me a wonderful quick tour of Alfama, as well as restaurant recommendations. He is an expert, and his advice was very valuable! The apartment itself was extremely clean, spacious, comfortable, and beautifully located in the best district of Alfama. I would stay there again in a heartbeat, and highly recommend it!
