I know this has been asked before, but a definite answer was not forthcoming.
I've looked on all the usual websites etc and can't seem to locate one.
Any help appreciated
There are no Serviced Apartment as such in DB. Several people rent out furnished apartment on a short term basis (sometime service is included). Depending on location and size of the place rents start at about HK$ 450,- per night. Have a look at the Classifieds of the "Inside DB" magazine. It's free and available around town.
