The initial address in the advertisement was not right.
After waiting for more then an hour at a wrong location a friendly local helped us to get in touch with Kai in Chinese. Communication in English is a bit difficult for him.
The room itself is quiet OK given the price and location , we found a lot of nice restaurants and shops nearby. However we noticed a strange smell and there is a lot of dust in the bathroom, the state of the sheets was kind of doubtful and the airco was not working.
