Manuel and Catarina were extremely generous and I really enjoyed my time there. I didn't get much time with them except for the first night, but Manuel had some great tips for seeing Lisbon's most important things within a day. I have to say it was perfect. In spite of the weather delaying me almost two hours, I still felt I saw everything I wanted. I'd love to return to Lisbon and if I did, I'd hope I could stay again with them.
