Our experience was fairly consistent with the rest of the recent feedback you’ll see on this page.
The check in location is not nearby, and you’ll need to hand over a 30 euro deposit if you would like more than 1 key - no matter your party size. You’ll also need to return the second key in person to get your money back, during office hours of course.
When we arrived, we found the washing machine and hot water were not functioning. We notified the host and they had someone over to fix the issue about 26 hours later.
Turned out it was a very simple fix, but going without showering or washing dishes or hands for that time was uncomfortable. We received a partial refund after Airbnb helped us mediate one. The host did not offer any refund directly, and did not respond to our regular attempts to find alternatives in the city for other washing or showering.
I would not likely pick this hosting group again. Not especially unresponsive or unprofessional, but you can find a better accommodation for similar pricing without any trouble in Lisbon.
