We had a great stay in Llanfair. The house was big and comfortable, with plenty of space for our two families (9 people). The kids (ages 5-15) loved the playroom, and the spa was a great hit with everyone. We enjoyed using the fireplace, and it was nice to have a dining table that fit all of us. It's a 15-20 minute walk down a steep footpath to beautiful Harlech beach, and Harlech castle (with a great little cafe) is less than 30 minute on foot (or <5 min drive). There's also a good community pool in Harlech for rainy days. Highly recommend for a big family or group!
