The hotel is right next to a major train line (aboveground railway, not subway), and the noise is tremendous (with window closed) and continues from 5am to around 00:30 at intervals of only a few minutes. Good sleep is impossible without very high tolerance of noise. We had a reservation for three nights. After the first night, we asked if we could cancel the remaining two nights, but the response was that no refund could be made which is ridiculous. Good location? Sure, only 5 minutes walking to Hakata Station. Room is relatively big at this price level in Japan.
