I can tell you that the good ones in the Philadelphia area are Pennsylvania Hospital, Bryn Mawr Hospital,and Friends Hospital.

However, to be admitted to them or most other hospitals, you need to be a clear danger to yourself or others or close to completely unable to care for yourself (can't work, eat or make yourself meals, haven't bathed in weeks, etc). Otherwise, they'll either not have a bed for you or your insurance won't pay for it. You also need an Axis 1 disorder (major depression, bipolar disorder, schizoaffective disorder, or schizophrenia) or most insurances won't cover inpatient treatment.
