If you're okay with basic comfort, this is a good option The apartment is at a walkable distance from most of Lisbon's downtown areas. This is another Airbnb place where no one actually lives, so we missed some comfort but if you're okay with sitting on stools and live out of your suitcase for a few days, no worries.
Communication with the host is very smooth and in our case, they were very accommodating with check-in (delayed flight) and check-out.
