We stayed in Dennis and Sue's flat for three weeks while on a medical elective at the Wairau Hospital, and had a lovely stay. The place was ideal for us, with easily enough space for two mates (one double bed each).
Sue was very welcoming when we first arrived (Dennis was away), and provided us with all the information needed. We really appreciated the two bikes -- they made getting around Blenheim very simple. With the bikes, everything was an easy ride away (supermarket, town centre, hospital). The location was also great for its proximity to the beautiful Wither Hills: mere minutes walk away. I ran there most days on the numerous tracks, which would also be great for biking.
The place itself is well equipped, with sufficient kitchen equipment to cook (no oven; wasn't an issue), and an extra fridge in the garage if needed so plenty of storage space. We appreciated the extra touches of tea, coffee, muesli, and other baked surprises. The local botanical bathing products were also lovely. The main living space was roomy, and opens onto a beautiful garden, with citrus trees we were welcome to. It was a peaceful, comfortable space to come back to. For two people it was spacious; it could fit at least two more without feeling cramped.
Overall, this is a comfortable, reasonably priced option in a beautiful region, with very friendly hosts. Thank you Sue and Dennis for a great stay!
