Wen Hui Hotel in Rizhao University Town has a good grade. A double room is about 150 yuan for one night, and there is another one in Wen Hui Hotel, which is a little cheaper. Now is the off-season of tourism, and regular hotels may reduce their prices. As for the hotels in the villages such as Xinhe Village and Dawa Village next to the university town, they are cheap, sanitary and not too dirty. They are all rural bungalows, and the rooms are not too big. I don't know if you can't adapt.
