Cidalia and Vitor were amazing, kind-hearted, welcoming hosts. We spent 2 nights at their wonderful apartment and it was a great experience. They even welcomed us with port wine and Portuguese tarts! On our first night in the city they also helped us find a table at a wonderful restaurant.
The apartment is located in a very central location, close to the city centre and subway stations. It is surrounded by good restaurants and bakeries.
I would recommend staying with the Santos Family to everyone. I know we would go back in a heartbeat!
