Paula's granny flat is a great place to stay. Comfy bed, TV, spacious bathroom and small kitchenette.
Self check-in worked and otherwise I had a private space for myself.
While there is no kitchen sink or hotplate, you can still self-cater, as they have a sandwich press and a electric frying pan.
There is a butcher just up the road and a supermarket within 15min of walking range.
It is a bit of a walk to the CBD (20 min) and the Omaka Aviation Heritage centre is about 45min on foot. So car or bike recommended, as there is no public transport in Blenheim that services the Aviation museum.
All in all great place and well priced. Would definitely recommend staying here.
