We stayed for 3 nights with Keith & Marilyn by the sea in Kaikoura. We had an independent unit attached to their home, with separate bedroom, lounge and shower room. It wasn't overlooked or conspicuous, so we could lay in bed or sit in the lounge looking at the view over the sea (and watching the seagulls)!
Marilyn provided a very nice, simple, Continental breakfast in our room each evening, which we could eat at our own convenience in the morning. We felt under no pressure to rush up and we much appreciated the chance to do our own thing.
Keith & Marilyn were very helpful in giving us advice about the area, restaurants, etc. Kailoura isn't the cheapest place in New Zealand, but we thought the Thai Restaurant was really good value.
