We've liked be there: cozy and quiet place with fast internet, so you can easily work on weekdays. Walk around on the evenings, because everything required nearby. And explore the city on weekends 'cause metro close to home too, so you can easy and fast reach any point, but we were wandering in the park nearby or went to Lisbon Zoo, City center, Parque das Nações and even Belém Tower by foot. The host is very kind and nice so I recommend to stay there :)
