If you decide to walk from the ferry to the Hostel you can take the 'Princesa Isabel' avenue until the 'Luis Ameixeiro' street and turn right and there you are. A good reference is the 'Frade' supermarket, when you find it keep walking to the second street right. Otherwise if you prefer to come by bus you can take any bus named 'Vila' and get off at the Frade supermarket stop.
