Как добраться до Sofia Chill House

There are bus stops right outside the bus and train stations. All of them stop at Rua da Sofia (where the hostel is located) except the ones saying 'Guarda Inglesa'.
They run every ten minutes.

To reach the hostel, you have to go through a store called 'Casa das Malhas', then just go to the 1st floor and there we are!
