Ubud lies in the centre of Bali and it is where all things spiritual and healthy and some normal unhealthy stuff takes place. A lot of ex-pats have settled and set up yoga and spa retreats and restaurants and cafes. I had hoped to take a beginners course in yoga and do some meditation, but my ribs were still broken and hurting, so all I managed was a run and 2 trips to the gym (which fucked my ribs again), during the week I was there.
I stayed in a great little guest house which was pretty central, but felt like it was in the middle of the countryside. It was surrounded by rice paddies and very peaceful. It was only £15 per night including a great breakfast and motorbike hire was £2.50 per day.
Here are some photos of where I stayed:

It was a great place to stay as there was always something going on in the rice fields, with people working and loads of wildlife. I made friends with 17 ducks that did everything together as one e.g. washed, fed, moved from place to place etc. It was like they had a sergeant major giving them orders to do stuff in unison .. they very very funny. I sat by the pool and watched them regularly.
