the doctor and the service have been absolutely first-class
My biggest worry before travelling was whether the quality of the surgeon would be as good as promised and if the final cost would be predictable. On the medical side, the doctor and the service have been absolutely first-class. I am in the early phase of recovery from my Haglund’s Deformity surgery, and I feel the surgeon handled my case with great professionalism. The care was excellent. The part that could be better, however, is the financial transparency. I was disappointed when the final price changed from what was originally agreed upon. This was a significant drawback for me and created a mixed overall feeling, despite the high quality of the medical treatment itself.

It was the right choice
The aspect that concerned me the most was the recovery process itself, but the doctor immediately alleviated my fears. During the consultation, he honestly discussed the healing timelines and clearly explained all the stages of the procedure and its risks, which helped me feel more confident. After the surgery, the clinic did not leave me on my own. They actively called to check on my well-being and provided very clear care instructions. No surprises. It was pleasant to see that there were no additional costs beyond what I had paid to the clinic. It was the right choice.

Now, during the healing phase, I feel better than I expected
What worried me most was how the recovery would actually go. But my surgeon was honest about the timeframe right from the start, and also explained all the risks and details of the laser procedure itself very clearly. It was easy to discuss any concerns with him. Now, during the healing phase, I feel better than I expected. It was really appreciated that the clinic staff stayed in touch and asked how I was getting on after the operation. There were no additional costs, which is also a big plus. Everything went smoothly.

I definitely recommend this hospital for treatments
Everyone starting with the coordinators, doctor, nurses were really nice and helpful, the staff care about their patients. The appointment i was supposed to have in another clinic was canceled because the doctor canceled all appointments on the surgery day, so the coordinator from bookimed (Natalia) reached out to Lokman Hekim hospital and they agreed to take me in the same day for blood tests and surgery next day, I am really thankful to dr. Hasan, nurses, Mr. Ismael, Olga and everyone, who took a part in my stay in the hospital.I definitely recommend this hospital for treatments
