My wife and I were visiting Portugal for our honeymoon. Our AirBnB stays in Porto and the Algarves were both lovely, but our last stay in Lisbon soured our experience a fair bit.
When we arrived, we noticed a strong moldy smell coming from the washroom and a fair amount of mold on the tiles and shower curtain. We didn't plan on spending a lot of time in the unit and thought we could tough it out, but that night my wife had a pretty bad allergic reaction to the point where her allergy meds didn't even help much.
When we reached out to our host in the morning, she was quick to drop by with her associate. We thought they were there to help resolve the issue, but instead our host got very defensive and said it was our imagination and our problem.
We had to book a hotel for the rest of our stay in Lisbon, and we reached out to AirBnB for assistance. Thankfully AirBnB was responsive, and they were quick to issue a full refund after seeing pictures of the mold.
Still, it was pretty upsetting that a large chunk of our last few days in Portugal were consumed by this charade and the host's ongoing attempts to message and argue with us.
We wouldn't recommend this stay - not worth your time and money.
