Personally, I'd go for apartments.
Hostels tend to be fairly basic with less privacyand hotels are a bit of a waste of money as they tend to include at least breakfast which if you're going out clubbing you wont be in a fit state to have!
Whilst I tended to eat out, it's still nice to have a fridge to keep beer cool and to store milk and fruit. Plus it gives you the option of cooking your own meals to keep costs down in order to save your pennies for the clubs (which you'll need!), although food is pretty cheap in restaurants anyway.
Also, Jet has a fantastic location but seems pretty dear if there's only two people in the room. Garbi seemed to have a lot of Germans there (which obviously isn't a problem) and a really shit nightclub which seemed to play cheese and were constantly trying to get the ladies in.
