The flat has arguably the best possible location in Lisbon, especially for tourists. Being right in the centre, you can walk to all the nice bars/restaurants within minutes, and the 28 tram is just around the corner.
André is a great host who keeps his flat extremely clean. Upon our arrival, he showed us everything about the apartment and started marking nice places in Lisbon on the map (he made the map himself), help us to plan the day.
Overall, it was a very positive experience. I would certain choose this place again if I visit Lisbon again in the future .
