Stayed here twice - nice enough. Stayed in the Cottage as well which is really nice. I would say the Cottage is worth the extra but it depends how many of you are going as the rooms are obviously bigger and the beds more comfy.
The pub next door is nice and its set in lovel countryside, agree with Jon that you will need a car to get to it though.
Chained Oak is in a better location as Jon says, more modern rooms, and may be a bit cheaper (not much). Alternatively, if you use the Sun offer code, you can get breaks in the AT and Splash hotel for not much more than staying in these places!
