We stayed here (family of four) for four nights in June and absolutely loved it. Balham is a bit off the usual tourist trail, but it's easy to get to (easy walk to train/underground) and there are several shops, restaurants, and a supermarket nearby. The apartment itself was great - exactly as you see in the pictures and description. Nick went our of his way to accommodate us after our inbound flight was delayed, and to make us feel welcome throughout our stay. Would definitely stay here again.
