Small, cosy Airbnb in a good location. Good recommendations of bar nearby. Pictures make it look bigger than it is. There is a double bed, and a couch bed but place would be too cramped for 4 people. We were only 2 people though so no problem.
Bed is very comfy - firm mattress but nice to sleep on.
Shower is good quality.
No Aircon so you would be very hot in summer but it was ok for us in November.
Check in and check out are accurate but we found a luggage storage spot so recommend you use that and then explore Lisbon while you wait to check in.
Host was responsive re questions (only tiny bin in kitchen so we had to find somewhere to empty waste but lots of big bins on the street so not an issue), and gave v good info for check in.
Good spot to explore Lisbon from.
