Luminita • Tympanoplasty
Romania

Verified review.
I highly recommend this hospital, doctor and bookimed for anyone seeking a tympanoplasty or other ear related surgery
Hisar hospital was great, rooms were large, clean and they had the latest medical equipment. The doctor (dr. Tayphun Apuhan) explained to us in detail the procedure (it was a tympanoplasty for my wife) and the surgery went perfect. The hospital staff was great, the nurses took very good care of us and the experience was a 5/5 at all times. The doctor also offered the least intrusive solution to my wife's problem so her recovery was quick and successful. The provided translator (which was needed as my wife does not speak english) was great and she guided us throughout the whole treatment phases. I highly recommend this hospital, doctor and bookimed for anyone seeking a tympanoplasty or other ear related surgery.
Our medical coordinator Olha was super helpful - she guided us through all the steps required, and the trip we had was great and un-eventful. The recommended hospital was great, we had a translator with us the whole time and the surgery was succesful

Thank you so much to the whole team for their clear, professional and heartfelt work!
I would like to express my sincere gratitude to Hisar Hospital Intercontinental in Istanbul for the high professionalism, attentiveness and care shown at every stage of my treatment. I underwent hysteroscopic removal of several endometrial polyps, including one large one measuring 3 cm. Everything went perfectly - from the initial consultation to the surgery and post-operative care. Special thanks to my doctor - Op. Dr Berna Buse Kobal. She inspired confidence from the very beginning, explained everything calmly and clearly, acted very carefully and confidently. After the operation I felt great, without pain or discomfort. The nurses and all the staff of the clinic were very attentive and helpful. The atmosphere in the hospital is clean, modern, comfortable and absolutely safe. I would also like to thank Julia, a Bookimed employee, who helped me with counselling and organising the trip. We made the decision literally at the last moment: we were informed from Dushanbe in the evening, flew out at night, and already in the morning I was in the clinic. Everything was organised perfectly - meeting, hospitalisation, surgery on the same day, and in the evening I was already relaxing in the hotel and feeling great. Thank you so much to the whole team for their clear, professional and heartfelt work! 💐 I confidently recommend Hisar Hospital Intercontinental and Bookimed to all women who are looking for quality, fast and safe treatment abroad.
Promptness, value for money. Approach.
There's no such thing

Julia from bookimed and I were looking at several options. We voiced our budget and special requirements. After studying our wishes, she suggested this clinic. The next morning we were already at the clinic after the appointment had been decided promptly

In my opinion, everything is just top-notch, starting with the doctor and ending with the staff
In my opinion, everything is just top-notch, starting with the doctor and ending with the staff. The transfer was well organized. An interpreter was provided, and the hotel was booked. I also want to express my gratitude to the coordinators, as they were always in touch. We even managed to make some good friends.
Competence of the physician, medical staff, interpreter, and overall everything is good ❤️

I recently underwent a procedure for my deviated septum, and I am beyond thrilled with the results!
I recently underwent a procedure for my deviated septum, and I am beyond thrilled with the results! I can finally breathe with ease, and the whole experience has been life-changing. The surgeon was absolutely amazing—so humble, professional, and incredibly skilled. The results speak for themselves, and I’m so grateful for the excellent job he did. I also want to highlight the fantastic support from Bookimed and their team. Maria, my coordinator, was exceptional. She was attentive, responsive, and made sure everything went smoothly from start to finish. The entire process was seamless, and I felt well taken care of every step of the way. Hisar Hospital was another highlight—clean, modern, and with a team of incredible nurses and staff who made sure I was comfortable and well-informed throughout my recovery. I could not have asked for a better experience. Bookimed is super reliable, and I highly recommend their services. If you’re considering this procedure, don't hesitate to reach out to them. From start to finish, everything exceeded my expectations, and I couldn’t be happier with the results!

MARCO MARTINEZ CONTRERAS • Cochlear implant placement

I am pleasantly surprised and grateful to everyone who took care of me
Excellent experience. I traveled from Mexico to have cochlear implant surgery. First of all, I found this hospital thanks to the attention of Bookimed, they attended me very well, got the best option and started the whole process. At the beginning I was obviously a little bit afraid that everything was real and correct and with good results, it was the first time I used this kind of medical tourism. I searched many countries and options and found the best deal through Bookimed at Hisar Hospital in Istanbul at the best price. Now that it's all over, I am pleasantly surprised and grateful to everyone who took care of me. I am impressed with how well they have organized everything for international patients. From the transportation, to the airport-hotel-airport, hotel-hospital-hotel, in all the appointments I had, more than 3 times in two weeks. The international department assigned me one and sometimes two translators, all were very well behaved, Dr. Yabuz Selim very attentive and professional, the hospital was excellent, the package included two nights accommodation in a room with two rooms, and meals for patient and companion. Pre-operative studies, post-operative follow-up, and only the agreed amount was paid from the beginning, not a dollar more we had to pay. I had never had this experience in a hospital before. The whole procedure was fast and without complications, they checked me 3 more times without any problem. They helped me resolve all my doubts and concerns, always with excellent response through whatsapp. I sincerely recommend and thank everyone involved in Hisar Hospital. I hope I never have to go back, but if I need to, I will not even look elsewhere.
Everything was excellent. It exceeded my expectations by far.
