Location is its strongest point - 5 to 10 minutes on foot to the nearest metro station (E. Nanjing Rd). Rooms are falrly clean and functional. Beware that one of the twin private rooms has a HUGE square pillar right smack IN THE MIDDLE of the room. Because of the size of the pillar, the twin room ends up being really tiny and there's not much space to move around (the attached bathroom looks so much more spacious than the room itself, relatively speaking!!).
Service standard is erratic. Some staff are more service-oriented than others so it depends on your luck who's on duty that day (oops). In terms of value for money, I can't say that the private ensuite rooms are worth what you pay for (except for the dorms which are basically quite cheap - like in nearly all hostels anyway). The common sitting/bar area is used for external conferences/presentations on some days so you won't be able to mingle with other travellers at that space during those period.
For better room facilities and services, there are cheaper and better alternatives (ie hotels) further away from the main shopping street.
