Quaint house. Clean spaces. Every morning, the ladies fusses over what they can get you for breakfast. Feels like being at a grandmother's house.

Lovely accommodation, with friendly staff who were very polite and helpful. The room was very tidy and clean, the only con would be the mattress was slightly uncomfortable with old springs. We overlooked that as the property was perfect for us.

A welcome in the hillside.
A lovely old-fashioned hotel in a stunning setting.
Comfortable, clean, cozy.
On arrival we were surprised to find nobody there even though we'd waited for reception opening time. Our keys were in a plastic bag pinned to a cork board. Explanations were confusing.
Breakfast was an epic adventure. The gas stove had broken down and a tremendous effort was made by staff to provide us with a very good Welsh breakfast that was well worth waiting nearly an hour for.
The lady who waited on us was very friendly and, at our request, talked about the region and how to get to our next destination. I'd like to thank her for all her kindness.
I was a little sad to hear the owner, I presume, telling her off for spending so much time talking. We really think this personal touch by staff is what distinguishes a good guest house like 'Llwyn Onn' from bland uninteresting hotels. Please don t discourage your staff from being so welcoming.
