Hi Scott -
I lived as an expat in Manila for four months. We stayed at the Ascott Glorietta. It is more of an excutive style apartments but the cost is still reasonable and offer large living space and kitchen/laundry in units which is nice. The breakfast buffet that is included is also great. It is attached to the Glorietta mall which is great. The Shang is across the street from this Ascott. Most of our short term visitors stayed at the Shang. The Shang has a great buffet in the hotel. This is a great location. It's very close to two grocery stores and taxi cues.
Can you give me more details on what your looking to do in Manila? I'd be happy to do my best to help.
