Great convenient place. If you've never used an electric water heater for shower, it's definitely something to learn how to use. It's not a gas water heater which means after the hot water tank is used, it needs time to reboil the water. This is what I did to maximize hot water time: before getting in shower, you need to turn on the water heater and let it finish boiling the water to the desired temperature (takes about 13 minutes), then first thing you should do after getting in is rinse yourself (and your hair), then turn off the water, put on soap and shampoo and face wash etc (which gives the water some more time to boil) and then rinse off and have some extra time in the end to join enjoy hot water.
The lady who cleans the room is also very nice. I've washed my clothes several times in the washer and she helped me hang them up.
Got to chat with the host a little bit and also met her daughter in high school. The host seems like really trying her best to make ends meet during this time when not as many travelers from mainland are coming to Hong Kong. I found out that even after the people she hires cleans the rooms, she herself will go to every room to clean and bleach the floors and everything to make sure it's up to standard because she knows Airbnb guests care about cleanliness a lot. With the current economy for hosting travelers in Hong Kong, she can hardly break even with her own rent costs.
