We had an amazing stay at the airbnb, the neighborhood is very safe and peaceful. It's indeed far from the center of Lisbon but they are a lot of bus station and honestly we preferred a calm environment.
The place had everything we needed with excellent wifi,it's perfect for 2 people and could even have a guest over.
Our host cristiana was very responsive and even let us put our language after the check out in their office louange,which was very considerate.
I recommend !
