Pedro's is a great host. Extremely welcoming and happy to help with any questions you may have. He also goes out of his way to help you out, for example offering me to store my bag after my check-out.
The apartment in Amadora (15-20 min from Lisbon city center) is of great value for money. While not everything is brand new, compared to a Lisbon city center apartment you have more space, have a kitchen with all utensils you may need and a great host near to help if needed. Recommended for longer stays, especially if you like to cook at home as well
