One of the biggest concerns for retiring expats to the Philippines is quality medical care (and insurance). Generally speaking, if you want a health care facility that is somewhat close to the type of facility you are accustomed to in your home country, the two main cities to keep in mind are Manila and Cebu.
Between the two, I prefer Cebu. Manila has the Makati areas which are nice but also about as expensive as living in a western economy. For some that is not an issue. Surrounding Makati is a lot of urban blight, traffic, smog and crime. It all depends on where you spend your time. For me, I'd rather hang my hat in Cebu, IT Park area. Yes, there are the same issues as Manila, but not as bad and not so much of it. Plus you can easily travel to other locations via the airport and/or ocean piers nearby.
But getting back to medical facilities, anything outside of Manila or Cebu is going to be substandard at best and similar to a MASH unit in some places. Especially the provincial hospitals, those can be downright archaic. They do what they can with the extremely limited funds they have, so if you want high quality health care, stick with Manila or Cebu.
There is now this new MAAYO medical facility which a fellow Philippines vlogger took the time to check out. You can view his video here. Hope you find it useful. :)
