Hey Gilbert - you need to explore Ubud a bit more. Maybe you are just thinking of Monkey Forest Road or the market. In the Campuan - Penestanan area, plenty of homestays are on paths where there are no cars or motorbikes, others are on paths with motorbikes, but no cars. Usually there is the sound of running water nearby - often from the irrigation channels that have small waterfalls built into them. Peace and tranquility - a perfect description.
Even on Monkey Forest Road, a resort like Komaneka (
Komaneka Resorts at Ubud Bali: Explore Hotels Resort, Honeymoon and Spa Accommodation) has bungalows with private terraces and plunge pools overlooking a river valley and rice fields - peaceful and tranquil and bloody expensive - but there you go.
