We are 5 (3 adults , 2 kids (3,5 yrs) will travel Hong Kong(15-19 Oct), how to go apartment Ovolro

For the apartment, do you refer to the one at 222 Hollywood Road, Sheung Wan?
If so, it is suggested to take a taxi to reach your hotel directly. The taxi fare is around 300HK$ for a taxi and all of you can stay in one taxi.

For the dim sim, you can go to the Central and Causeway Bay area to try to find some restaurants.
