Salvador's place was great for us and our kids. The kids stayed in the two single beds and were quite happy. The location worked especially well for us. While it is not in the center of Lisbon, we had driven our car for the vacation and found it convenient to park near Salvador's apartment even though we arrived in the evening.
We walked around the quiet neighborhood to the bakery, grocery store, and restaurants. We drove up to Sintra on one day. We grabbed an uber to the center of Lisbon to visit sights there. We drove around Belem to the different sights there.
A great place, great location, an easy stay. Thanks Salvador!
