We stayed at Smokey Cot for 1 night as we were attending a wedding at Miskin Manor (rooms there are £120). The rooms were big and clean with a modern bathroom. The owners were very welcoming.
It was quiet and peaceful. Breakfast was nice and cooked to order.
If arriving here by Sat Nav or using sites like multimap beware that it sends you slightly the wrong way. Seach for the road name instead.
The only other thing that could cause a problem is you do not get your own front door key. This wasn't a problem for us as we checked in then spent the whole day at the wedding.
It is also only a few minutes drive from St Fagan's.
