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.

The service was great and the staff was incredibly friendly, making me feel welcome right away
The service was great and the staff was incredibly friendly, making me feel welcome right away. The main point of difficulty for my basic check-up was the internal logistics. The process involves a lot of walking around and checking the availability of each department as you go, which can be quite time-consuming. It really would have been better if a specific time had been allocated for each service in advance to streamline the day.
Great service, friendly staff,

The surgeon and the entire team at the clinic were great, which put me at ease
My biggest worry was centered on one of the 2-3 fibroids I had. The surgeon and the entire team at the clinic were great, which put me at ease. The procedure itself was smooth. I am now in the early recovery phase and I feel good, though I do tire easily, as is expected. It’s still too early to know what the final results will be, but I am optimistic. I can’t really comment on the price clarity as I wasn't sure about the details. From a medical and care standpoint, everything was handled very professionally by the staff.
The doctor was patient and heard all my needs. He couldnot have done more.
Bookmed helped me get the best options. The process was so smooth
Maybe, letting customer know there will be additional cost other than the ones quotated. We paid for so many tests not covered.
