My journey felt "perfect"
What stood out most was the surgeon's personal approach. He showed me exactly what would be removed and set very realistic expectations for weight loss, which built a lot of trust. He even visited me personally after my sleeve gastrectomy. My journey felt "perfect". The care was solid. The main challenge was communication, as the "language could improve" among some team members. From a practical standpoint, the final bill had no surprises or additional expenses. I stayed in the hospital for more than six nights, and the clinic has remained easy to reach since I left, which is a great support during this recovery phase.

The staff were a definite highlight, providing excellent support and guidance throughout the PET-CT with Gallium 68 PSMA scan
I came away with a positive overall impression of the day. The staff were a definite highlight, providing excellent support and guidance throughout the PET-CT with Gallium 68 PSMA scan. They made me feel looked after. The doctor was professional and the clinic itself was well-equipped. My only negative, and the reason for a lower overall score, was the airport transfer. The taxi was difficult for me to get in and out of. More importantly, upon arrival at the airport, I could not find the driver at the designated meeting point, which created unnecessary stress. While the medical care was handled very well, the logistics of the transport could be improved.

The organization was top-notch
The consultation with the doctor and his calm confidence greatly helped to manage my anxiety. I went through the examination calmly and confidently, feeling a professional and compassionate approach at every stage. The organization was top-notch. The coordinator was always in touch, promptly resolving any issues that arose, and the transfer was always on time, which was very important. The clinic is excellent, and the staff is caring. The doctor himself is polite and attentive. Thank you.

I feel better than expected
My biggest fear was the language barrier in another country, but everyone made me feel comfortable and heard. From the coordinators to my doctor, the treatment was professional and humane. My surgeon was particularly good, visiting me after the surgery and explaining realistic outcomes beforehand. I feel better than expected. I was given a clear aftercare guide, and there were no surprise costs. My advice is to stay for about five days after the procedure before you plan to travel home.
My experience was very positive; it exceeded my expectations, since being in another country with a different language than the patient's is often frightening, but there I felt comfortable because at every moment I felt listened to and treated with a lot of human warmth — from the coordinators, the translator, and especially the doctor, who was very professional and humane in his treatment. A very beautiful experience.
