Elsa and Rui were great hosts - the apartment is lovely (though in one of Lisbon's hillier residential areas - I recommend using Uber instead of the tram, as it's super cheap) and we were collected from the airport by Carlos, who told us loads about the city. It was a great way to arrive! Elsa was on hand via email throughout our stay, which was useful, and was flexible about check out time, which was also a huge help! Would recommend!
