Ricardo was an amazing host. Not only was his flat beautiful (and huge for 4 people!), but he was exceptionally kind. He gave us a number of recommendations for fun things to do in the city, showing us on a map even though it was quite late in the evening, and he was always available if we had any further questions. The flat was also perfectly located to both popular tourist stops and fun late night bars. I would definitely choose his place again when I go back to Lisbon.
