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.

He is the one that made this journey an amazing, wonderful, magnificent adventure
Starting from the beginning. My international coordinator maurice did an amazing job in getting me the best doctor i needed for my procedure. Traveling to turkey 🇹🇷 was an incredible experience very excited. At memorial sisli hospital my local coordinator fatiha was very forthcoming with all the details, took care of everything. Then my translators Mohamed and beyza also very helpful and professionals great job helping me understand exactly what was being said. Last but not least. The most important part of the experience. Doctor.. Mustafa akarcay. He is the one that made this journey an amazing, wonderful, magnificent adventure. The doctor is top notch, did a wonderful job. Thak y you doctor Mustafa again am so happy with the results. Will recommend him to anyone who is considering plastic surgeron in Istanbul or anywhere in the world. Blessed and happy .

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

This created an impression of a professional and well-prepared approach
Our son is 6 years old and has been diagnosed with ASD. We arrived at Memorial Şişli Clinic on Monday. On the same day, we had a consultation with Dr. Betül Tavil. The doctor carefully examined our son and immediately began asking questions, to which she seemed to already have some answers. This created an impression of a professional and well-prepared approach. After the consultation, the doctor recommended stem cell therapy. With our consent, the cells were ordered immediately, considering they would be delivered to the clinic within three days. On the same day, we provided four vials of blood. Three days later, the stem cell administration procedure took place. The total dose consisted of 50 million cells: 1% was administered into the spinal cord, and the remainder was given via intravenous infusion. The procedure itself lasted approximately 10–15 minutes and went smoothly. Afterward, a supportive IV drip was administered to the child. Overall, we stayed in the hospital for about 4–4.5 hours, after which we were discharged. At this point, we have observed no side effects in the child.
Prompt service, and the doctor, Betul Tavil, is very personable and I confidently say she is truly a professional in her field.
About Bookimed service
Our experience collaborating with Bookimed was very pleasant. Communication was easy and clear — our messages were always answered promptly, all issues were explained in detail, and helpful advice was provided. When necessary, Bookimed representatives contacted us by phone, which was particularly convenient and reassuring. It felt like they genuinely wanted to help us, rather than just respond formally. Thank you to the Bookimed team for your support, attentiveness, and human approach. We are left with only positive impressions.

There is now hope that it will be possible to help her in the future
I am grateful to our translator Irina, who arranged an additional consultation with an ophthalmologist, and we received another opinion regarding my sister's vision. There is now hope that it will be possible to help her in the future. I hope that there will be new discoveries in the field of ophthalmology.
My sister had consultations with a maxillofacial surgeon and an ophthalmologist, and underwent examinations. We need time to monitor her condition and changes in her vision in order to choose the best option for her situation.
About Bookimed service
Once again, medical consultant Katerina is helping me with organising consultations, examinations and treatment. Katerina is always available and helps to resolve any issues that arise during the process. I recommend Bookimed, who will always help you find the best option for resolving your medical issues.
