Lots of great things to say about this place:
1) Location was superb! As soon as you exit the building is the MTR station, this is great when you want to stay out of the HK heat. There are also plenty of cafes and fast foods within a few minutes of walking. Temple Street is also walking distance!
2) Cleanliness: The room is really, really clean. There are helpers who clean, replace your towels, and mop your room everyday! They also give you water bottles, which saves you a few dollars from having to buy at the convenience store.
3) Laundry amenity: It seems the helpers used the laundry machines every morning to wash sheets and towels, so I would use the laundry at night. The machines are very clean and there are laundry detergents, hangers, and clips available.
4) Building: The actual building is quite old and some may feel put off by the appearance, but once you get to the floor of Mei's Airbnb, it is completely renovated!! She even put shiny tiles in the outside hallway to differentiate her Airbnb from the rest of the building. This is difficult to explain, but you will understand once you see it - it is truly appreciated.
Other comments: During my 10 day stay, I only saw Mei once, but she recognized me immediately and even had a nice chat with her. She is really sweet and wants to make sure your stay is comfortable.
