How about Sanmen Island Hotel?

The hotel has no electricity during the day and generates electricity at night. There is no TV to watch. There are bugs on the bed, which is annoying. A male staff member quarreled with the tour guide and called names behind others' backs. It was really speechless. The only advantage is that it is close to Moon Bay Beach, so it is very convenient to go swimming. The water is very clear, although it is a little dirty, hehe. Occasionally a little mouse will come out and run by the sea.
