About 4 years ago my family stayed at Hostal El Molino in A Guarda (southern most point of the Rias Bajas). I know that they had a website, but I can't find it now. It was beach front, faced the river Miño/Portugal. Beautiful view. They had both rooms and "apartments". This place was very "basic" meaning not at all luxurious, but had the necesitities. And it was cheap for the location it had. It was on Playa Camposancos and was about 2km from town.
