I stayed at this hotel because I was studying to get my diving certificate at Aiqian Dive Shop.
advantage:
1. The pier and dive shop are also downstairs, so it is very convenient. After each study, I immediately go to the room to take a shower. 
2. There are several restaurants downstairs (but the prices along the row of restaurants along the coast are a bit more expensive) just downstairs, so eating is very convenient. 
3. I booked a sea view room with a balcony. Everyone must book a sea view room. There will be more sunshine here. If you are a diver, you must book a room with a balcony to dry your clothes. (The balcony on the 1st floor is the largest. The room card says 1st floor, but it is actually the 2nd floor)
shortcoming:
1. There is a bar downstairs, and usually the cheers and singing don’t end until 11:30, so friends who go to bed early must not book here. Night owls will really enjoy it. 
2. The room is indeed very small. There are two beds and only a small passage. However, the environment in Semporna is like this. I think it is acceptable to be mentally prepared. 
3. We stayed for 6 nights and there was no cleaning. We asked the staff to change the garbage bags ourselves.
4. There are few choices for breakfast, but it can barely fill your stomach. 
Summary: If you have booked your itinerary at Aiqian Dive Shop and usually go to bed after 11:30, there is nothing wrong with booking here. You must get a sea view room with a balcony. The sea view room does not have any fishy smell of the sea. It is worth recommending.
