The Yellow House is in a great location. You can come in from the airport on the subway for under 2 Euros and walk about 10 minutes to the house. This will give you a flavor of the neighborhood and the square. From here you can be in most parts of Lisbon within 10-20 min walk, depending on how fast you are. I loved just exploring the neighborhood. As a host, Cristina could not have been more diligent or more accommodating. She was always very quick to respond to all communication, and she had great suggestions for my stay, including the suggestion to visit Sintra on Friday and avoid the weekend. She was, of course, exactly right. She left thoughtful details such as a bottle of wine, fresh fruit, orange juice and so on. In and of itself, the place and the wonderful host are 5 stars, but I gave it 4 because of the one element Cristina has no control over: there is a popular club across the street. I wish I had known that. Be prepared for that, and you will have a great time staying at the Yellow House, and I'm betting you will find no more accommodating host.
