if you are alone, just book it. It is perfectly located and the communication with Patricia is super fast. And if you travel with somebody, just make sure to book another one of her LX apartments. The style is lovely, it is super clean and if you need anything Patricia will help you right away. She definitely deserves to be called a super host ;-)
And regarding Lisbon, I've been there many times, but I am still amazed every single time. A lot of things are happening constantly, the city is always changing and regarding the times we are living in, LIFE is already happening again there!
