Whilst I haven't seen the apartments myself, I recently spoke to some people who have stayed there and here is some info they have told me:
1) It's located on the border of sheung wan / central, and convenient to local shops, but next to a freeway-like road so very noisy and smelly. 10 mins walk to most places in central. BUT It's not an expat area, when compared to somewhere like midlevels or places next to the lower escalator.
2) It's a mid to high rise building about 5-8 years old. (They weren't sure if this was exactly right, but they guessed)
3) Beware - The rooms are very small I have heard. Nowhere near the 555 sq ft they quote. More like 300 sq ft. (U have to be careful in HK, they sometimes have 'suspicious' practices, like counting bay window areas, lift lobby, even the lift itself in the quoted sq ft).
4) The advantage is that they are one of the cheapest serviced apartments available in central (around 15K). I'm sure you can negotiate the 20K down.......unless ur apartment is on the top floor or something.
Hope this helps. If anyone else has other info, please post here !
