Stayed here for a week in July with 2 small children. 2 nice bedrooms and spacious balcony. Really out of the way so nice and quiet and lovely views of the mountains.
The family who own it live next door and were very friendly, welcoming and helpful. They also spoke immaculate English which was a great help! As the property is attached you could sometimes hear each other but not hugely intrusive.
Really easy to reach local towns and beaches, no more than a 10 or 15 minute drive to several great locations (beach, Ribadesella, blow holes etc). Lots of great beaches, Picos de Europe, dinosaur museum within 30 mins drive so really good location.
I'd recommend it as a good value place to stay.
