I'll second that recommendation. Very convenient, clean and not expensive. Close to the bus, close to the harbor.
To get to the harbor (starting point), turn right out of the hotel entrance and left when you run out of street: As you reach the "square", turn right on Ruá Igrexa, and it is more or less straight on to the harbor. There are several cafés on the harbor front, where you can get your first stamps. I got the best cafe leche of the entire trip at café Sarga.
From the square towards the harbor you'll (just after the next intersection) pass a church on your left. The building after that is the market (Mercada da Magdalena), where you can forage for the day. It opens relatively early.
