I’m so very glad I had the best doctor and best care

My arrival at Istanbul airport was smooth and efficient. I was met and transported to my hotel. My hotel was lovely. Transportation from hotel to hospitals on time and efficient. I met my advocate at international patient area, she had everything under control, all tests lined up and doctor appointments were fabulous. My advocate translated to my language at every appointment. I’m very happy with the service and I felt very “looked after”. My outcome is excellent and I’m so very glad I had the best doctor and best care.

Whether it's the doctors, nurses or reception staff, many other hospitals should take inspiration from the Turkish hospital model

The quality of the hospital service is second to none, with well-organised, highly competent services that are always available to patients. Whether it's the doctors, nurses or reception staff, many other hospitals should take inspiration from the Turkish hospital model. The hospitals are like luxury hotels, you feel good, you are looked after and followed throughout your stay. Finally, the money I spent there was really justified. Thank you to everyone who looked after me during my 14-day stay. Of course I recommend Istanbul Memorial Hospital. Antonio. M

But I really liked the Bukimed service - they helped, supported, organised everything in the best possible way

There are certain issues with the hospital, in particular, the staff who are in no hurry and we had to spend the whole day in the hospital instead of a few hours - we waited, waited, and waited again..... But I really liked the Bukimed service - they helped, supported, organised everything in the best possible way. Thank you.

Overall, the hospital is good

Perhaps it's due to a different mentality, but we didn't really like waiting endlessly - no procedure or appointment started on time, no one is in a hurry and no one appreciates other people's time.

I honestly had an amazing experience

Having breast reduction and uplift surgery is something that I had wanted for numerous years but due to underlying health conditions I knew it wouldn't be straight forward. When I eventually made the decision I couldn't have made a better decision. From the initial contact and liason s from Bookimed to the transfers, hotel, hospital tests, surgery and post surgery support was more than I could have asked for. The interpreter Bayza was exceptional and made me feel relaxed throughout the process. The hospital staff and especially my surgeon Dr Kadriye who was so friendly and professional throughout. I honestly had an amazing experience. All my health issues were taken very seriously and accommodated for by giving me the relevant tests and aftercare. I would advise from my personal experience to take clothes that button or unzip after surgery .And my must have item would be my neck cushion that I took with me for after surgery for when you have to sleep upright. Memorial Sisli was outstanding. And I am so happy with outcome. Thankyou all . The photos were from the morning of surgery and the 7th day after.

The reassurance,confidence, understanding and professionalism of surgeon. And of course the outcome!

The food on the ward.
