The 2-room apartment is accessible from the HK airport by taking the Cityflyer A21 bus, which seemed to have increased its frequency so the owners didn't expect us to arrive early.

The apartment is located right in the middle of Mong Kok shopping district. Right below the building is the Ladies' Market (Tung Choi Street), there is a supermarket and few pharmacies nearby. Eateries are everywhere within walking distance.

Zoe and Andy explained everything clearly about the apartment & its facilities, but also provided some food recommendations around MK.

Pros:
The owners are fluent in Mandarin and English.
Very convenient location
Bright apartment, with good views of Mong Kok area
Clean apartment
Everything is provided as mentioned in the description
Wardrobe (plus cloth hangers) in one of the rooms
Condiments provided if you are doing small cooking

Cons:
Apartment looks smaller than expected (well, this is HK)
No broom & mop provided (So we can do a bit of housekeeping)
Rusty electric kettle...
Go through many doors in order to get access to the apartment (including the security gate downstairs)

I have a very enjoyable stay and I will book other rooms hosted by Zoe and Andy for the next trip to HK. Thanks again!
