Breakfast was cooked to order and well looked after with excellent service .
Helpful information given about the local sights and nothing was too much trouble.
Can’t think of anything. Would stay here again and thoroughly recommend. Moyra, the host, went out of her way to be friendly, hospitable and helpful

The location of the Guest House is Perfect, 5 minutes away from Merthyr and Bike Park Wales right next to a historic reservoir but it could be a million miles away, its location is amazing, the Property is quiet and clean, the staff are so helpful around breakfast time.
The room is also serviced, amazing for a property that is a B&B, price amazing value for money.
Nothing, the property does exactly what I expected.
