I have moved from Luoyang, and stay two nights. One day for Kaifeng, and one day for Zhengzhong. I got fast train for Beijing from ZhengzhouDong station. It is so modern and confortable.
Not a place with all of extra amenities but the room is clean, has everything I need, wifi, great breakfast for a modest price, quiet and location is near enough to easily getting around the city and stores like Walmart and Dennis nearby. subway about 25 minutes along the riverwalk.
