I visited in early July with family as a group of 8. Normal check-in was at 4pm, but we were allowed to check-in earlier at 2:30PM.
The location was great. It’s about 25mins from downtown Lisbon, and has several food options nearby (See Mercado de Alges). We did hear quite a bit of noise at night though from people outside. It was a weekend, so it made sense I suppose.
The Airbnb was smaller than expected, but clean when we arrived. I’d say it would be much more comfortable for 6 people rather than 8.
There weren’t any toiletries when we arrived, so be prepared to bring some of your own.
Overall an alright stay.
