Georgia Harley reviewed What an amazing experience

What an amazing experience. Like most, the idea of travelling to another country for a medical procedure was nerve wracking at first however, my amazing care co ordinator Sean was there every step of the way! I arrived on the 31st December and everything from my booking experience, hospital stay, pre op tests, gastric sleeve surgery , transport home and post op assistance has exceeded alp expectations. I am from the UK and all of the care far surpassed anything that I have recieved in the UK. Sean has also been there post me returning to the UK to check in and respond quickly to any post op questions that I have had. Would 100% reccomend

Had a bit of a mix up but this was easily fixed and my feedback taken onboard for future patients 😊 The hospital is immaculate with very friendly and caring staff. I was very well looked after before and after surgery. After surgery nurses would check on me every 1.5/2 hours and if I rang the bell they would come instantly. Translators were brilliant and the staff who didn’t speak much English was very good with google translate 😊 The care and the cleanliness at the hospital I went to Medistanbul was out of the world. Puts the UK hospitals to shame honestly! Had so many family & friends telling me don’t go abroad for surgery but it’s the best thing I ever done! My coordinator Rick Miller was so quick at responding, always kept me up to date and was very helpful throughout the whole process. My surgeon was Prof Dr Kagan Katar who was very professional, he came to see me before and after operation Also the transfer driver Orhan was amazing he was so helpful with our bags in the huge airport and sorted us out with wheelchairs Had a brilliant experience

customer reviewed Dr Ahmet - arm lift and Sr Emre - face, neck, eyes. First class

I had arm lift surgery with Dr Ahmet on 8 October 2024. David Turker was my co ordinator. From the collection at the airport to dropping be off ;I also had dental implant and my partner has a hair transplant) everything went smoothly. They’re organised and efficient. There are several interpreters and staff who work for Booking Surgery who are resident at different times in the ward of the hospitals. On 30/1/24 I returned to finish off my tooth implant and to have a deep plane facelift, a neck lift and upper eyelid blepharoplasty. Again everyone was fantastic. My only critique is the hospitals’ food, which, similar to UK is not great but I knew that prior to going and found out where the nearest shops were. I also ordered in pizza via the helpers and they got me stuff from the shop. They also got me a soft pillow as the pillow on my hospital bed the second time was like a boulder with wee pebbles in it LOL. But this is a minor thing and plenty of cheap pillows for sale nearby. I felt that my treatment in Istanbul was better than any I’d ever received in the UK and I’ve had over 5 operations in Scotland. The nurses in Turkey are so kind and compassionate. Any medication you need for any ancillary issues that arise is readily prescribed to you. The surgeons are lovely too and experienced and professional. I had Dr Emre Koçman for my face etc., ab older guy in his 60s with great experience. I’m not 10 days post op and pleased Ruth progress. I’m 65 and once healed I'm going to look 45. That wasn’t my aim but I’ll take it LOL ! Thank you booking surgery. You’re the best. Maxine
