Cristina and Andre are wonderful hosts, and they really went above and beyond to ensure our stay at the Yellow House was as pleasant as possible. My wife and I had a chance to spend some time with them at the beginning and the end of our stay, and it was really a plus to be able to chat with them. The apartment was spotless!!! It is located in the residential area of Principe Real, and Cristina was always available (email or SMS) to give us any information we asked for about restaurants in the area, transportation issues, etc. There are indeed 3 or 4 very good restaurants nearby, and a small supermarket just 50 meters away. Lisbon being what it is (hills everywhere), it is a climb to get to Principe Real from other neighborhoods: if your are not into walking, there is a bus stop right near the apartment. I highly recommend the Yellow House if you wish to stay in the Principe Real area: Cristina really cares about the well being of her guests.
