I was once in Home Inns Zhangjian. It is a three-star hotel. Not bad except the location - it is located at the end of Zhangjian Hi-tech Park.
Again I booked at ctrip.com for a Home Inns nearby Tsinghua University. The price is CNY170 per night. It is not so close to Tsinghua actually. The location is in a poverty zone. You definitely agree China is a developing country if you look around the hotel. The mattress is not firm. The room is not sound proof. The toilet flushing next room sounds just like in your room. The worst part, it has mosquito, in March!
