In reply to An Triubhas:
We stay at Llanrwst at Carneddau Cottage. It's on a farm and only 1 mile from the centre of Llanrwst. The cottage is a lovely converted granary. It has 2 bedrooms so sleeps 4 but the price seems to be the same as other cottages in Snowdonia that sleep 2. The farmer and his wife are great. It has a combi boiler so there's always hot water which in the winter is excellent. You can google the cottage to get the owner's phone number or book through the Wales Tourist Board. They do offer less than 7 nights if available. You would really like it.
