If you're looking for a clean, conveniently located, simple accommodation, Ishitas place is a good option. Her place is about a 20 minute walk to the temple bar area and is in a safe area near the bus stops.
We never met Ishita, her husband came to greet us in front of the hotel. He was very pleasant and helpful - he provided us with an iron, blow dryer, and towels. He gave us recommendations and showed us what was in the area.
