The experience and professionalism of the Doctor has been unbeatable
I had a stomach reduction with Dr. Batman. I can only recommend this Dr. and the Hisar Hostel. I was very pleasantly surprised. I must admit that I had moments of doubt, of fear that they did not comply with the sanitary measures or that there might be a problem. But the whole process from start to finish was excellent. The hospital has nothing to envy to the best private hospitals in Spain, the experience and professionalism of the Doctor has been unbeatable, I had been given good references from Spain (other great bariatric doctors). And the most important thing is that they are very involved in helping you to make sure that everything goes well, even after the operation, once the year of follow-up starts. The only problem I have, which I think they need to improve, and which I saw in other opinions before deciding to go for it, is that you ask for a translator in Spanish and he never appears. In my case I speak English, but I was accompanied by my mother who doesn't speak any English and I would have appreciated having a Spanish translator at times when I was dazed by the medication. If it were necessary they should offer it, even at an extra cost. I would have paid for it
Professionalism and empathy of the doctor. The facilities and professionalism of the hospital and its staff. The hotel and the room we were offered. The follow-up at all times of the process.
I did not have a Spanish translator
About Bookimed service
The experience with the hospital and Hisar was excellent, but I think Bookimed has a lot of room for improvement. First of all, they need more staff to follow up with patients. At the beginning I was being attended by a chatbot and when I saw other opinions complaining about the same thing, I demanded to change to another coordinator who spoke my language. From that moment on I was attended by a person, and although I have no complaints, I have lacked a little more follow up. So I give an 8 because the hospital has a 10 and bookimed a 6. But without bookimed I would never have found this hospital, so I am very grateful, I hope you take this constructive criticism to improve in the future.

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.

I am very satisfied and have already recommended it to my friends!
I had a VIP checkup at Hisar International Hospital, I liked it very much! The process was efficient, I went through all the examinations without any delays. Modern equipment, experienced doctors and friendly staff. The interpreter Rabia accompanied me everywhere and translated everything very well. I also had lunch at the hospital, delicious! The general practitioner at the end gave me a general assessment of the results of the analyses and gave me recommendations. I am very satisfied and have already recommended it to my friends!

If they can improve on having Doctors who speak english or a good translators. Also the cost quoted to a patient when booking should be maintained instead of bri ging other additional charges once you get to the hospital. They should also confirm things in advance instead of saying yes just so you can make an appointment and when you getvthere the service is not available. This wasted a lot of my time.
The hospital's willingness to.pick and drop me off. The cleanliness of the hospital.
The delays in waiting to be attended to despite making prior booking, unavailability of a vaccine which the hospital had confirmed to be available, delay in getting a driver to drop me back to the hotel and poor translators.
