Spacious and sunny!
We visited Isobel in February and had a wonderful time. The house is in a fabulous location; literally 3 minutes walk from the Botanical Gardens and the Cable Car. Parking in that area (it is near a University) for anything other than a small car is a challenge and you can be in the CBD in minutes if you like walking, so consider avoiding a car if you can.
The courtyard gardens (front and back) are beautiful. The side access and stairs might be a challenge for those with mobility issues or large amounts of heavy luggage, but then again the whole of Wellington is steep and full of staircases.
The space is well set up and, as advertised, clean and bright. It is a large room with helpful amenities like a small fridge, iron, first aid kit, etc. Isobel left many thoughtful touches such as tourist brochures, small chocolates and tips, such as where to put the coffee grounds if you use the coffee plunger.
Perhaps the best tip of all was the recommendation for the local restaurant. Definitely worth it!
It was very easy for us to settle in and just as easy to clean up and go. We highly recommend it for anyone looking for a central location from which to explore Wellington.
