I ended up staying 11 nights with Norma at O'ong bungalows and would highly recommend her bungalows to other travellers. She's a fantastic person with gorgeous humour and a heart bigger than her wallet (which is not equally true for the others along the path). Prices are negotiable, especially if you plan to stay longer.
She's located near the end of the path past Rubia Tirta, actually right after Ohlala Cafe. The bungalows along this path are all more or less the same in each price category. Some slight differences in toilet type, wall material and location. Norma, while having a kitchen, some staff and a big porch with a large table, she doesn't offer a la carte food.
BUT, one of the main reasons to stay with her are the fabulous family dinners she cooks up every night. Instead of your average restaurant where everyone sits at their own table ordering their own food, Norma cooks a big buffet dinner for everyone staying with her every night. The food is awesome home cooked Indonesian food and theres always enough to make everyone stuffed. The food is enjoyed together around the big porch table, so it's the perfect place to meet fellow travellers and to exchange experiences and get new ideas! The family dinners were the highlight of the day, every day!
Norma has at least 10 bungalows with different standard. From tiled floors and western toilet to plastic carpet and squat toilet. Some are down by the water, actually over the water, and some are a bit higher up the hill, but still only 10 meters from the sea. As far as I know, all beds are equipped with good mosquito nets and all bungalows have a hammock on the porch. Some have showers, others only scoops and a water basin. After one week, Norma offered me new sheets for the bed. She's also very helpful with arranging transport and other practicalities.
The island is a zoo with monkeys, goats, horses, geckos, cats and dogs and some make more noise than others. Especially the geckos and the monkeys can make some noise from dusk to dawn (the monkeys will only walk over the roofs to get to the trees by the sea), so light sleepers may opt for earplugs.
There's no WiFi at O'ong, but neighbouring Ohlala (20 meters away) has WiFi that sometimes also ranges to O'ong. A SIM-card with 3G is also very cheap to get.
