For the price, location , comfort and friendliness this place is really excellent. Comfortable beds ( not rock hard ) quiet at back, decent breakfast, very cheerful, friendly, helpful staff with some speaking english and fast free WiFi. I was very impressed and made welcome from start to finish. It is easy for me to recommend.
Ok, this is not a very fancy hotel. No thrills, no little extras, no nice lobby or great view from the window. But for 20 EUR a night, including breakfast, I am not sure you can find anything better in Rizhao. Next door they have a great steak restaurant.
