Shang ? Well, if you are looking for FLs and have the talent, just do a hop, trot and jump to Green Belt/Havana, Spciy finger etc.

And of course, P Burgos is not far off.
Well, if you know which places you will visit, look up on Agoda or booking.com for a central place.
For me, I prefer to stick to Makati Ave, as a) I am comfortable there, and b) there's a mall to buy stuff in Makati Ave - A-Venue mall, and c) easier to get girls to come there and d) P Burgos is just 5 minutes walk.
Putting up in place like Malate, well, there are a lot of street kids and taxi drivers trying to jack up the price- problems you generally don't face in Makati.
But if your work is mostly around Manila, then look for a place in Manila - depending upon budget.
However, again, be careful of Manila traffic, it can take 2 hour just to cover 10 KM, or 15 minutes for the same distance.
As said, use Agoda or Booking.com for map view and sort- it will be easier.
If in Manila, I try to stay in Rivera Mansion, Mabini street, as it is very near Robinsons Malate - where you get occasional FL and there are some food options. And the Hotel also has a decent kitchen.
Makati - I stay in Citadel (No kitchen) or Great Eastern. Other cheaper places are terrible - no comments.
And, forgot to say, I go on low budget
