All of HKG's downtown areas celebrate nightlife, but Soho and LFK have become the default area for expats who are blind to the stupid prices charged on everything. You might want to look at Causeway Bay or further off the hill to Sheung Wan for sensible prices and less effort.
Your best friend will be the mid level escalator. You should know that it goes downhill to 1000 and uphill from 1020. Walk through IFC Mall to Hang Seng Bank and start the escalator a little further towards the peak from that bank. Get out at Staunton St. and walk along until Elgin drops off to the right. You'll spot the convenience store on the corner, and the fruit stalls and other street vendors catering to the Filipina maid community. The sewing shop folks will not always be there. Lulu will instruct you on how exactly to get the key as there is a good chance she will be out of town.
Read the reviews on using the shower. We had no problem. Flick the switch just before entry to the bathroom a few minutes before going in, and go easy on the flow and you will be OK.
You will want to quiz Lulu on her and the area's approach to recycling.
Wifi is pretty good, but the router may require resetting if the signal is flakey.
Nearest supermarket is hardly super, but it's there ... up a steep slope to Caine St. above you, and it is called Wellcome. You will have spotted Marks & Spencers on the escalator, but this is a premium place for the homesick expats.
A sensibly priced dinner can be had closeby at a Vietnamese place called Bun Cha. Breakfast you will want to self-cater as not much is open until 1000.
It's a long and windy road around to the Peak Terminal if you are going that way. A few cafés along the route charging stupid prices so pour your own coffee unless you are trying to prove your net wealth to someone.
