My mother and I had a lovely time in Penestanan, Ubud. Villa ESA was in a nice quite location just around the corner from Alchemy. Komang got us international adapters and a hairdryer to use in the villa during our stay and the pool was a generous size for 2 people! You can walk through the ricefields to the big Bintang if you need supplies for the kitchen but there are plenty of yummy warungs and vegan/raw cafe's in the neighbourhood. Plus a taxi service and Round Bar/Cafe just a minutes walk away.
I would definitely recommend Villa ESA if you want a no fuss, clean and friendly home stay in Ubud.
