I thoroughly enjoyed the design of the room. I stayed at their standard room, their bathroom looked great, the wall behind the bed as well, it had a lot of wood incorporated which I loved. The thing that stood out the most was the high ceilings. I think it would be pretty difficult to find another hotel with ceilings this high in Hong Kong, so it was a pleasant surprise. Cleanliness was top notch, didn't notice any off sights or smells. Amenities were standard, nothing special. They don't provide bottled waters, instead they have a pitcher of water from their water filters. I suggest you to ask them for a new one because you don't know how long it's been sitting there. While I think that the area The Olympian is located is somewhat secluded, as in there's not much to do/see, the nearest MTR station is about a 8-10 min walk so it's not terrible.
However there were a few things I thought weren't up to par. The most important one is the air conditioning. While there is a thermostat inside the room for you to adjust, I cranked it to the coldest and it was still not cold at all. I'm not sure if this is affected by the high but it felt like only a fan was on. The bedside controls for the lights and curtains were sometimes unresponsive. One of their TV channels had no sound. Their bathroom drainage is terrible, water takes a long time to drain. It came to a point where the shower flooded out into the hallway, the whole place was wet.
Overall not bad, may stay again.
