We stayed I the villa in last august and just loved it!
It have two big bedrooms, one with a king bed and the other with two single beds. As we have thee children, they put an additional bed in the second bedroom and still there was enough of place for children to play. Every bedroom has its own bathroom.
There is a huge living room with an open kitchen. I have not cooked there so don't know if there is enough of equipment for cooking, but certainly enough of plates, glasses etc for 5 people.
All the room facing the sea and the swimming pool. Very beautiful view.
Actually Kubu is a very quite place and there is nothing to do, except for snorkeling and diving. The sea bottom in front of the villa was just amazingly beautiful.
The villa located right next to a small hotel (it's not a part of the hotel though). And we had breakfast and dinner in the hotel's restaurant. They also delivered food to our villa, and we could enjoy it on the beautiful terrace.
