By car with or without driver is the easiest. Motorbike.
Though I have seen people arrive by bemo and bicycle.
There are quite a number of clean, cheap places to stay amongst the rice fields or with valley views. The water palace also has rooms.
There are some small restaurants around the main square or eat at your hotel. The food is cheap and tasty though it takes awhile to cook. A good sign that the food is fresh.
The water palace (Taman Tirta Gangga) has beautiful gardens on various levels and two pools for swimming, one for locals and the other for tourists. Water is cold and clean. Goggles are fun as there are fish and crabs in the pool. there is an entry fee for the gardens and another entry fee for the pool.
There are walks around the rice fields with or without a guide. The guides are very informative about the local culture and the plants of the area. There are great views over the rice fields. This is a great place for the rice field photos.
Talking to the locals is very interesting as they are very friendly.
Best Points: quiet, pretty, nice views, ricefield walks, water palace gardens and pool.
Worse Points: none
