Highly recommend staying at Sergio's! We stayed at two other Airbnb apartments and two hotels during our stay in Portugal and Spain and our time at Sergio's was by far our favorite! He kindly let us check in an hour early and met us to go through the process and present us with a very thoughtful and extensive Lisbon guide that we referred to many times during our stay. Many great restaurants within walking distance and convenient to city sights. So happy we stayed here!
