Unique experience. We were picked up at the airport by our host's cousin, who gave us a map of Lisbon and gave us all sorts of SUPER useful tips (the best miradouro to have a view of Lisbon, although not a touristic one !).
There was literally nothing we needed to worry about buying (salt, pepper, sugar, tea, coffee, wifi, tissue, all the basics). But if we did, there was 2 commodities shops right next to the place.
Our host remained available at all times and was very helpful and cheerful :D
Thanks a lot !
