We spent several days at Villa Gajah and had a lovely stay. The villa is spacious and would work well for families or small groups. The bedrooms are air conditioned and the common areas are open air with lovely views. Wayan and Suri, the couple that runs the house, are very friendly and helpful. Wayan walked us to a nearby restaurant by taking a "short cut" through the rice terraces. We certainly would have been lost without his help. Wayan or Tono, the house manager, will bring you to and from the villa on arrival/departure and will take you into Ubud. They will also handle laundry, food delivery, spa services and more. They make everything very easy. Finally, the pool at the view is amazing. It is large for a private villa and has such a pretty view. It was very relaxing.
The two drawbacks, or just things to be aware of, are the walk to the property and the lack of privacy. There is a bit of a walk to the villa from the car and it is tough with large suitcases. If you have mobility issues, this may be a problem. Second, with Wayan's family living on the property and the very open nature of the house, there is a bit of privacy that is lost. Neither issue should stop you from booking this lovely villa, but they are things to be aware of.
Overall, we would not hesitate to book Villa Gajah again.
