I have just booked by email with Puri Bambu Hotel in Kendonganan, Jimbaran. We have stayed there twice before and really like it. Their internet price is 45US per night,per room for 2 of us, and includes breakfast. This is a small hotel in the middle of the village of Kendonganan and five minutes walk to the seafood restaurants. The rooms are big and spotlessly clean with T.V. and movies (I think) Restaurant prices are good and the food was nice. The staff were friendly and most helpful. The pool is pleasant with a swim up pool bar. They have a free shuttle to Kuta.
Anyway why I really posted this was to say how prompt and efficient their email booking is. I had a reply straight away. They also pick up from the airport.
