I was with my mother. There is no stop in whole 12 hrs journey where a women can pee. Kaushambi is very bad bus station, no passenger toilet were open, a guy was showering in a newly made toilet and told us that this toilet is closed and there is no water. Their DRM is very bad person and doesn't take passengers seriously. bus stoppage after hapur were worst. However at hapur stoppage was good it was named shiva the Dhaba.
Final words, it was not ur fault but u should also share stoppage and facilities provided there.
Hope I never have use bus services from there ever again.
