This flat is really good located if you wish to stay around EXPO, a new and very nice quarter of Lisbon. However, a ride to the old part of the city takes about half an hour off peak hours. The flat itself is very spacious - a family of four or two couples should have no problem in that regard. It is reasonably equipped, though some more kitchenware would be nice. It was not very clean. There are restaurants, cafes and supermarkets nearby and beautiful parks. We didn't have any contact with Luis during our stay. All in all a good experience with some room for improvement.
