If you’re planning on using this place for two people it’s fine, but not for more.
The only things that were good about this place were the location and the communication with the host.
The bathroom was not clean at all, it was a bit disgusting to see fungi in the shower and in the ceiling of the shower.
The place is tiny and the noises from the street can be heard inside as if they were inside the building. On top of that you get to hear the neighbours...
Having stayed in other airbnbs around Europe, we must say that we are a bit dissatisfied with our choice for Lisbon.
