If you are just looking for a sleeping space in the heart of a shopping area, this guest house is OK.
It is a guest house, not a hotel.
Room is tiny, bathroom is very tiny.
But the surrounding area is pretty safe.
Girls can walk around safely at night without any hassle.
It is Causeway bay anyway.
A huge 24 hours open supermarket is only 2 minutes walk. And loads of shopping centres, restaurants around.
Great part is that Victoria park is 100 meters away. Surely you can do a lot of activities.
So.... Good budget guest house.
