We had a great stay in Casa da Estefanea. The self check in system is wonderful and works perfect. A very cozy room with excelent beds. We stayed in a room with a window facing the street, but you wont hear any noice, because is a very quiet area.
Next to the hostel, there is a place where you can buy traditional crossaints from Portugal, so it's a perfect stop before you head to the beach.
I would only recomend the host buying new hand towels and keeping an eye to the cleaning, specially in the bathroom.
Beside that, it is still a place where we would like to visit again.
