Be aware that construction is always happening in Hong Kong. The apartment is adjacent to a construction project so there was noise 24/7. Absent this nuisance, my friend & I enjoyed our stay. The apartment is close to the metro line of Sai Ying Pun (make a right out of apartment, cross the street, find Eco Tree Hotel, and there's the entrance). We found some good, inexpensive restaurants (hole in the walls)...one was a 30 second walk and catered to the locals (it was our favorite) (head toward Ibis Hotel and it is before the end of sidewalk).
Once we found the metro line, it was easy to hop on the metro and explore Hong Kong. The airport express was awesome, easy and efficient. Don't forget to buy an Octopus card and refund it at the end of your trip! Have a great time in Hong Kong!!!
