We stayed for 11 nights in April 2019 for the Omaka Airshow. The space is roomy and all on one level, and ideal for longer stays and self-catering. The beds are very comfortable indeed, too.
Sue and Dennis were very welcoming and kind, and their thoughtfulness made our stay a delight.
All in all, we highly recommend their apartment, and would definitely stay with them again if we return to Blenheim.
