Yu's apartment was fantastic!
Spacious by Hong Kong standards and very clean which was much appreciated.
One small word of warning: we weren't prepared for a small flight of stairs to enter the building. We had really heavy large luggage which was a mission, so be prepared! There is a lift to take you up to the Airbnb after these stairs, however and a very friendly security guard/doorman who greets us sometimes :)
The apartment utilised the exisiting space to the fullest with many mod cons and great little attentive touches (that coffee maker was a godsend!). I know it's not very important, but we really enjoyed the quality of tableware too.
While the beds are fold outs from couches or the wall (in the spirit of making the most of space), they were really firm and comfortable so please don't let that deter you from staying here.
It's located just a stone's throw away from Sheung Wan train station, the ferry station and walking distance to a few famous places to eat in Central as well. Really recommend trying out the Hoi On cafe, a very OG "cha chaan teng" which is literally downstairs from the apartment. Get the hong kong milk tea, you won't regret it!!
Yu gave us very clear and easy to use instructions to reach the apartment which was really helpful. Trying to find a place with a taxi in a foreign city could be a little daunting.
Our host was always attentive and responded to questions quickly and tried to help us with questions to the best of his ability.
We had a really great time in Hong Kong and we were so lucky to stay at Yu's awesome Airbnb and we would definitely stay here again.

P.S. Please please go check out the rooftop (level 14), there is a pretty decent view day or night!
P.P.S. If you need anything electrical (we needed power adapters) take the train to Wan Chai. I got a power adapter for only $10 HKD rather than falling for the usb chargers they had in 7/11 that were going for $180 HKD
