I highly recommend! Amazing location, great communication and very easy check-in. Antonio and Rui were so friendly and flexible with me as my travel plans changed last minute. Baixa-Chiado is central / walking distance to everything you want to see, and the neighborhood is very safe and has cute restaurants, cafes, and shops all around. The stairs were not an issue at all -- even though the apartment is on the 4th floor, it's only 4 flights of stairs, not 8 like it is in the U.S. This airbnb was so clean and has everything you'd need!
