This was my first time when I made the booking on AirBNB and Olga and Joao made everything seem easy. They guided us on what transportation should we chose from the airport, and of course they waited us even the hour was late (approx. 12 PM). The house is very big (exactly like the photos on airbnb) and filled with personal stuff. They also provided local tips on what to visit, what to eat, and how to have a general good holiday.
As a CON for the location: the wi-fi doesn't reach the entire house (but this could be considered also a plus because it will gather the entire group in the livind room); also the neighborhood is not central, but it is very safe and quiet.
As a CON for Lisbon: the airport is very near and you will hear planes from 6 AM until 1 AM.

P.S. do not miss the Mercado and pastelaria Aloma which are nearby.
