I cannot recommend Margie's wonderful "cottage" enough. After dropping us off and picking us up from our biking wine tour they gave us a quick tour of the town offering great history tidbits and recommendations on restaurants. The cottage itself is everything you'd need and after coming from the Tongariro crossing the previous day a night in the spa with the beautiful wine we had purchased was the cherry on top of a perfect visit.
If you're looking for a place to stay in Napier this is absolutely it!
