We (couple plus twelve-year-old) stayed here for four nights in late August. Can't recommend it highly enough. Couldn't ask for a better location – literally just a few steps away from the beach and Carbis Bay train station. The property has lovely views over St Ives Bay, and is impeccably well kept – it's exactly as pictured.
Everything you need is inside, including washer/dryer, dishwasher, kitchen appliances and utensils – even a coffee machine. There's also a supermarket nearby (3 minute drive / 20 minute walk).
Would definitely stay here again.
