We had a lovely one night stay in the terrace room. The apartment was very clean and had everything we needed, plus the bed was very comfortable. The room is quite small for two people (the other two bedrooms at the back are bigger) but it didn't bother us. It did get pretty hot though as the sun was shining on the terrace all day, but I'd still pick this room over the others due to the light and the view (the other rooms have no window). Location wise it's perfect, lots of cafés, restaurants and bars nearby, and Graça offers spectacular views over Lisbon.
