Our stay with Stefano and Patricia was amazing, not only was the space new and very clean, but the hosts were also incredibly welcoming. They will provide you with a list of places you can go in Lisbon, and believe me you need it! They will also be there for additional questions, and generally help you get around the city with useful advices.
The apartment was very well situated and we didn't have to travel for hours to get to the good places.
Overall even though we were not the biggest fans of Lisbon, we were very glad with our choice of an air Bnb.
