Sai Ying Pun is one of the oldest areas in Hong Kong, a place the British military called home when they first arrived and an area of great charm. These artsy neighborhoods are filled with coffee shops, bars, yoga studios and art galleries. The up-and-coming neighborhoods of Sai Ying Pun in particular are attracting more and more working millennials. The flats are small and the buildings tend to be old, but given their proximity to Central, the rents are fairly pricey.
