I love Lisbon's architecture and how the younger generations are reinventing the old. New specialist shops have popped up in the area and it is great to see unique retailers which cater to every taste. Praça Luis de Camões works more or less as a hub. By night, you'd go towards Bairro Alto and its many restaurants and bars. Bairro Alto Hotel has a fantastic rooftop bar and is perfect to watch the sunset. If you go towards Chiado, it would be wrong not to indulge in a bit of shopping.
