You can find much better places to stay in Lisbon. The furnishings were mainly beat up pieces reminiscent of a frat house or well used university residence. No lid on the toilet tank- simply missing. No hooks or toilet paper holder in the bathroom, which was poorly lit. Each person gets one lumpy, thin foam pillow. In general, the place in reality is not as nice as the pictures. But the worst thing by far was that the bathroom had an terrible sewage stench. Clearly a significant plumbing problem. Worse, we messaged the host but he did not respond until I followed up again 10 hours later (I should add that he said in his response that he did not get the original message, but it was sent through AirBnb). He also responded saying he had no idea about the problem, but I notice prior reviews also mentioned a bathroom stink issue, so....Also, the serious problem would have been obvious to anyone (the host, or his staff) properly inspecting the property between guests.
Also: this place is located in an area that is VERY noisy with people drinking, partying etc. right below you on the mostly pedestrian streets - until the wee hours. While it is true that the windows do close out a lot of that noise (though not all) there is no AC. Even in October, it was pretty stuffy to have the windows shut tight all night - but that's what we had to do.
