Liliana's place was a wonderful stay for our party of 5. The location can't be beat in terms of proximity to the best destinations of Lisbon. The place itself was clean and spacious: good for lounging around before/after a long day of exploring the city. Having AC is a welcome luxury (note, however, that one bedroom lacks AC), as is in-unit washing. Finally, Liliana was great to work with anytime I did have issues.
There weren't many cons. It is a fourth floor walkup, and the place is quite old, with various things being unstable (stools, tables, doorknobs etc). But they didn't meaningfully affect my stay, so I'd wholeheartedly recommend this Airbnb to anyone looking to explore Lisbon for a bit!
