Rooms are nice, very clean, and you have your own security safe that's big enough for plenty of things (15" laptop plus bag lays in flat, plus plenty of space above it also). You have your own curtain for privacy and to block some light. In practice it's separated by male/female, I'm guessing it's only mixed when everything's full and there's an uneven ratio.
The front desk is very helpful, very caring. They have a huge lounge area with microwave, mini oven, sink, silverware, tables/chargers for doing work, electrical adapters, etc, so working and living is all covered. Other guests also seem very nice.
The location isn't in the city center, but I found out is actually more convenient than you would think. There's a bus right downstairs that goes to Mong Kok MTR, and a bunch of buses that go pretty much anywhere in Hong Kong. If you like to walk, Mong Kok is 2km away, and TST and Ave of the Stars is surprisingly only 3km away, so it's an interesting walk if you happen to want to explore. I took a bus to Causeway Bay also, which was only 20 minutes and a direct route that didn't require any transferring.
There's a lot of food options around also, and much cheaper than in city center areas. $50 can get you a very nice meal, and I found a roast duck place and dumpling place very nearby that I couldn't resist going back to several times. Tsui Wah pineapple buns with butter are also amazing.
