This is the type of place that gives Airbnb a bad reputation.
1) The apartment- the entrance and walk up to the apartment are in poor / dirty condition. Then the apartment itself had broken floorboards which “they just noticed”. The apartment is also quite dark, with no real windows in any but one room. While the place is close to a nice mirador- the view from the apartment looks mostly on some trash cans and construction. The check in process was also not smooth as we had to wait on the street for 30 minutes even after confirming our arrival well in advance.
2) The real problem was the noise in this apartment. With very cheap / thin walls- we heard extremely loud construction, a piano inside the building (sounding like we were sitting next to it), and the bedroom sits basically in the neighbors apartment and sounds like there is only a thin curtain separating the rooms.
3) We noticed the disruptive noise in the apartment right away, and asked whether the construction would soon end- if not we would have to cancel. Depending on who you asked, you would get a different answer- but the motive was clear, they would say anything to keep us from canceling the rest of our stay. We wish we had simply canceled our stay, as it was not only the construction in many units around us, but the neighbors and street noise made for a very frustrating stay. We understand that the construction is outside of the hosts control- but being led to believe that it would not be a problem going forward (very much not the case) strongly impaired our ability to work remotely. The noise woke us up promptly at 8AM all 5 mornings of our stay.
In the past months, we have lived in 4+ Airbnbs in Lisbon and many more around Portugal- this place was our worst experience by far.
