I am soon going to Hong Kong for a weekend
Can anybody recommend a nice hotel, as I am a single guy I would like to be close to entertainment areas.

Eaton Hotel is not bad.

3 words. Chung King Mansions.

Just make sure you get a tetnus shot before you go.

Try to make sure you're staying on the Hong Kong side.

Both Mandarin Oriental are within short walking distance to LKF.
UpperHouse is nice, at Pacific Place on top of the MTR Admiralty station, which can take you almost anywhere.

HK has many 5 star hotels, but vast majority of them are old pieces of sh1t that desperately need updating.
If you give a budget, I will try to give you the best choice.

No really budget since the company will be paying.
I havent been to HK for 12 years so I have no idea about costs.

Somewhere from 1000 to 1500 RMB should be possible I guess.
