Reviews
The place is clean, there are not many children, and the facilities are suitable for children under 6 years old
The environment is clean, there are not many children, and there are teachers present to guide the children, so there is a lot of interaction! Although the venue is not big, it has all the facilities and is worth going!
There is no wind or cold in the upper activity area. It is very hot. I hope it can be improved.
Although the place is small, it’s a pretty good experience. Klook is convenient and quick to buy flights.
First time coming here. It's clean and tidy. My kid love it
職員好友善，場地細唔緊要去之前已經知道，但冇預過咁唔乾淨，啲玩具冇人抹過咁，好多塵
My sister at work is very caring and will interact with children and help you with your needs. However, the environment and space are relatively small and the range of activities is affected.
唔覺得值依個價，太細又無咩設施，設施舊玩舊，完全無性價比，一個字（差），唔會再去，因為相等值錢仲有大大大把選擇
There are not many people at this venue, and the equipment is very fun, especially the slide and the trampoline.
Although the venue is not big, the facilities are fun. There are on-site kindergarten teachers to accompany you. It is also conveniently located near the West Rail station. I will go there again next time
