I thought with such beautiful pictures and only 3 comments compared to other accommodations from the host that the place would be new. This is not the case. The place was used a lot in the past, the carpet is missing, the green plant also the sofa is covered with huge dirty marks, the shower, one pot, the radiator in the bedroom and the bed are partly broken. I would also mention like already pointed out by previous travelers that the all building is very humid. The fridge is also very very very loud which does not allow to spend quality time in the living room. I left carottes outside of the fridge for one day and they started to get mould. My shoes where all cold and humid after the first night because I left them in the living room. I had to fix the bed base myself to be able to sleep, by removing the mattress, putting back the bed base and putting back the mattress, and to be honest I never had to do that, and when you pay for a place to be clean (35€) you expect it to be cleaned which was not the case. I have found hair from previous host in the shower and in the bedroom as well as a hair band.
When I mentioned all of this to the host, he offered to give me a refund for remaining nights (even if my first 2 nights were already not the expected standard) however with heavy lockdown in Lisbon I just had no other place to go to and decided to stay until the end. No goodwill gesture was offered, so I am warning here next travelers.
The communication was slow when I needed urgent replies. I have the feeling the host do not care about the place they are putting on Airbnb.
Positive sides of the story are, the flat has a nice bedroom which you can warm up with the radiator and this is useful during winter, the light from the window is very nice. And the bed once repaired was not so bad. I had no issues with the wifi. The kitchen does have all required kitchen utensil, the washing machine is properly working. The flat is in the heart of Alfama and I could come in morning to leave my luggage before doing the actual check in later in the day (even if the host failed to inform me that the flat was ready).
If you ignore the awful smell and the humidity in the living room, all the mentioned flaws of the flat and live only in the bedroom like I did (being a solo traveler) you can enjoy your stay. Otherwise just go somewhere else because this place is too expensive to be booked only for one bedroom.
