LADIES:
You want to stay in a street where 99% men only from all over the world (no Europeans) are on the street? And around the corner substances are being taken and sold?
The noise from the street in your room is 'impressive'? And a fellow girl arriving said: "Oh my god, it is sooo dangerous here! I do not want to go out!"
Yes, the room itself is nicely done. And most likely nothing will happen when you are out.
You decide for yourself if you want to have this experience and impression on your joyful stay in Lisbon.
I would not have booked if I had been aware what the surrounding would be.
And: I left after 20 min. I chose not to stay there. Very happy I didn't.
