“The cottage was easily found by SatNav (many of the local roads are single track), and was warm and welcoming on arrival.”
Both heating and wood burner worked well. Bedding and towels were clean and fresh. I had no phone signal, but that's likely to be provider dependent. There are no street lights and it's quiet-which we love. The neighbour feeds the birds, so we were lucky enough to see woodpeckers at close range.
WiFi was excellent (important for the WiFi dependent offspring). Bathroom was of good size, warm (it had both a heated towel rail and radiator), and the shower was excellent.
We used dishwasher and washing machine: both of which worked extremely well (though we couldn't find instructions in the cottage-luckily there was WiFi). You should be aware that the kick board hadn't been cut out to allow the dishwasher door to open easily, so the door does rise up and over it-making it feel as if you've broken it-but it is fine.
There was a good supply of cutlery and crockery (often lacking on other cottages, which often only give you one of each item). We like cooking so found kitchen pans & utensils adequate but not extensive, and did wonder if they'd be sufficient for 5 like minded-adults (we were a party of 3 adults).
Under counter fridge was of good size (with a small freezer at the top-useful for ice cubes and a bag or two of frozen goodies).
Neighbours friendly but not intrusive.
Excellent walks within 10-20 minutes drive, and only half hour to Elan Valley.
Our only disappointment was that we didn't find the games which had been mentioned in the description (luckily we'd taken our own) and that we had to come home.
