I was staying Bridal Tea House Hotel in Hung Hum last time and it was about 5minutes walking distance to the LRT Station. It's clean and recommended, the price is cheap as well, consider is a budget hotel. But, it's only recommended for 2 person because the room is freaking FIT FIT.. lol!

Bridal Tea House Hotel got a lot of branch in Hong Kong, perhaps you can find out them and see which location you prefer to stay. As long as it's near to LRT station, any places are convenient to you.

Here is a list of hotel, perhaps you can compare the price and also location.

Enjoy your trip!
