Gt: a good option is : Diamond park inn, just when heading to the center on the left side.( busstation and night market 5 min walk.)
Great parking for the bikes, and very good clean rooms about 500-600 baht a day.(Hotel is 1 half year old)
Another option is Wiang inn hotel, just heading to the center on the right side, 1 min walk from the busstation and nightmarket.
This is my personel nr 1 choice, thought little more expensive: about 1500 baht a day incl brfast.
Wang come is also a good option and its on the left side, just when passing the pizza hut, you see a sign: wangcome hotel, go left and there you are.Parking for bikes no problem, roomrate 1450 incl brfast.
Have a pleasant stay!
