What clean and affordable hotels are there in Qingdao?

I don't know many hotels, but I know some. Because some students came to stay and train for 40 days years ago, I'll tell you a good one. Qingdao Free Bird Guest House can stay for more than a week and can reach 60 days. It has a digital TV and a bathroom. It is estimated to stay for 2 days, 80- 100 a day. Because you are here to play, you can't stay too far. It has two houses. It is equivalent to Chang 'an Avenue in Beijing. Hehe, the phone number is 85759230-5. The second dormitory is near Qingdao University. It's not far from the sea, either. Not bad ~!
