I have now stayed in Sewin with my husband and three young children (aged 5, 7 and 9) several times. What keeps bringing us back?
Firstly the accommodation is extremely spacious and comfortable. The room that the children share is large enough for them play in as well as sleep, meaning that when we're having down time in the cottage they have their own space. The large kitchen / diner / seating area is very well equipped so we need to take very little apart from the food we need. The second bedroom is also huge, really comfortable and has amazing views.
Secondly, the location is perfect for what we like to do. The beaches of Tenby, theme park at Oakwood, Folly Farm adventure park and zoo and our new discovery, Pembrey Country Park with toboggan, horse riding, beach etc is a are all within striking distance. Nearby Carmathen has all the shopping you need.
So it's a place that works very well for us and our family needs at the moment. We shall return in the Summer.
