Martinborough is a great place for wine lovers! The hotel has a good location amongst vineyards. You can ride a bike to most of the wineries.
Rooms are big, very comfortable, very nicely furnished and have a great hot tub! Also the kitchen is very well equipped and there is complimentary expresso coffee in the room.
Breakfast was excellent, with many options of fresh fruit, eggs, toasts etc.
Although the rooms were very clean, they maybe should pay a little more attention to the outside balcony.
We had dinner one night at the restaurant and were not too impressed by it, and we thought it was too expensive, comparing to other excellent restaurants in the neighborhood. The wines in the room are also a bit overpriced.
While you are there, you should definitely drive do Cape Palliser, which is about one hour away and absolutely gorgeous!
