I've been staying at the Jupiter Suites, on Jupiter Ave, Makati for two nights at the start and two nights at the end of my current trip. I can highly recommend them. They are in a great location by the crossroads of Makati Ave and Jupiter, the rooms are immaculate, modern, well furnished, great bathrooms and huge. They include breakfast for two and will do a deal on the price, mine should have been 3600 a night inc taxes, but I got them down to 2500 which is good in Makati, considering some of the alternatives on P Bourgos Street. The staff are all typically friendly Filipino's. There are plenty of decent places to eat on Jupiter Ave, and Greenbelt is only a 5 minute walk. I'll definitely stay here again next time :-)
