This is a tolerable apartment.
Positives: The bed is very comfortable. The air conditioner is powerful and cool; there is also a good air purifier. Overall, it was easy to keep the air fresh. The washing machine is good: quiet, quick, and easy to use. The location is brilliant: roughly equidistant between Austin and Jordan stations, which gives you very good connections. There are also plenty of shops nearby. It is also near to Kowloon Park, which is an extremely pleasant place.
Moderate: The apartment size is ok for a single person or couple. The location is safe (this is Hong Kong, so the location is safer than almost anywhere in the world) but seedy. Not a great place if you're a single man and you're not looking for a "massage". The walk-up area is ok, but with occasional bad public hygiene e.g. food left on the stairs. The area is moderately noisy. Right now, the noise is bad because of someone refurbishing a flat at night (for some reason) but that presumably is not a permanent problem.
Negatives: There is a moderate insect problem. This problem is easy to contain if you are sensible about tropical hygiene, e.g. you keep surfaces clean and don't leave any food open. However, on the first night, I had to kill a whole nest of ants and a significant group of cockroaches (about 5). That was an unpleasant "welcome to Hong Kong"! There were also several messy places, e.g. the plates and cutlery were not properly cleaned. Some more dish-cloths would be good for longer stays: for some reason, these are not easy to find in HK. Checking-in was a problem due to the system used - there are much simpler ways to keep an apartment safe while still doing self-check in. This also caused a problem on the last night, when I needed to contact the host to enter the apartment.
Final positive: Gloria is very good at responding quickly. So, if you do have a problem, she will be very helpful, very quickly.
