My experience from this hospital is since last 2 years.
We visit Rainbow for our 4 year old son and are quite satisfied.
Many of our friends visit Rainbow hospital for their children.I found it to be a neat and well maintained Hospital.Staff in the out patient clinic is good.Wards and rooms are neat and clean.
Team of doctors is young and energetic.Typical balding old timer doctors are no where to be seen.
One of my friends daughter was admitted in childrens ICU with Dengue fever last year.Dr.Farhan and his team took good care.She was very serious and was treated very well.
I dont know what more would you want from a hospital, you can not expect to give you a hotel like service in a childrens hospital.
New born ICU is also big with many small babies with so many problems, getting good treatment.
I can say this with confidence as when my friends daughter was in Hospital we used to meet many parents with small babies admitted in the ICU and we found all of them satisfied with medical treatment.
No doubt best childrens hospital in Hyderabad.
