pros:
great location - right off the main tourist strip so you are close but not too noisy
ac in bedroom works fantastically
had cooking supplies
bathroom was fine
cons:
ac in living room was broken (this is where the sofa bed is)
no sheets, blankets, towels or pillowcases provided for person sleeping on the sofa bed
we slept 3 people "comfortably" I think you could fit 4 MAX if the sofa bed people are small. no way this sleeps 5
checkout was a bit odd, they required us to take out the trash and leave the key on the table instead of in the lock box, not sure if this is standard practice in Lisbon
summary:
if you are a couple looking for a quite place centrally located, this place is great. but if you have 3 or more people I recommend avoiding this airbnb
