Try Eden in Central, HK. 8 mins walk fm Central Mtr Stn. Lower half of Wellington St heading towards Sheung Wan, on the left.
It is considered a luxury motel, also IS a regular hotel, and hourly room rates may not be available sometimes.
Take the bigger / more expensive rooms to impress yr GF, fm what i gather of yr msg. Range $500-$700 for 3 hrs, but you got nice comfy rooms, discreet service. You can book it as a hotel too.
Hope this helps, happy shooting !
