We decided to walk to playa ballenas to see which accommodation felt good, since it was low season and lots of places felt a bit abandoned. So we ended up staying at Colibri, which had lots of people enjoying themselves (and not only pensionados like at other places in low season). The place is right at the beach, has a nice bar on the beach, the people are really friendly and helpful, breakfast is simple but delicious and the atmosphere is exactly what you expect from an accommodation at the beach: summervibes all over the place. The apartments are large and spacious, with good kitchen equipment (even a blender for a nice smoothie). Best choice on playa ballenas if you ask me.
