From the very beginning of my enquiry at Bookimed to the last taxi ride to the airport after the procedures, everything went without a single obstacle

I was on 29 September 2025 at Lockman hekim clinic for breast and eyelid reduction.All my fears and doubts were in vain. From the very beginning of my enquiry at Bookimed to the last taxi ride to the airport after the procedures, everything went without a single obstacle. Everything went smoothly and smoothly. We arrived very early, we were taken to the clinic and our interpreter Olga was already in touch with us. We were placed in a beautifully decorated room, on the same day all the necessary medical parameters were taken. The doctor clearly explained what would happen and how it would be done. We were in the clinic for 3 days and then to the hotel. It was also clean, beautifully designed, rich breakfast. I recommend Lokman Hekim and Dr Marat Yaman if you want to change your appearance.

Food, staff, I can't single out anything, everything was good.

Thankyou for changing my life and giving me some confidence back :-)

There is nothing I didn’t like from the moment I contacted bookimed ! They found the PERFECT surgeon for my personal needs and my surgeon delivered at a great price! I am very happy with my results and after care, I would highly recommend the hospital my surgeon and bookimed. Thankyou for changing my life and giving me some confidence back :-) DR Esme GUNBEY is beyond talented in his field and a really nice guy too with good English :-) I’m already thinking of what to book next ha

The hotel is spectacularly clean and modern, my surgeon DR Emre GUNBER is a perfectionist and the work he done to my nose after 2 failed rhinoplasty’s is incredible! Many surgeons I spoke to previously wouldn’t even take it on, He was honest from the start and said it was a high risk surgery. But I’m amazed at the results and the after care and advice given! Would highley recommend my surgeon for any ENT operations and would highly recommend the hospital and booking.med as a whole.

Thank you so much 😊

I am very grateful to all the staff for their attentiveness and prompt assistance. I travelled alone, but I didn't feel lonely, I had support from all sides ☺️ Transfer is super, I didn't even expect that it would be so VIP, the drivers are very well-mannered, attentive, careful driving! The hotel is great, I got even more than положено👍🏼 The interpreter Olga provided all kinds of help, support and was always there for me! 🫶 I had a difficult operation on my nose, but Murat Yaman is a professional and did everything to the maximum and even more, I do not regret that out of all the options I was offered I chose him 🥰 I hope my nose will be beautiful) Thank you so much 😊

Transfer, ward, doctor, interpreter, hotel, staff

Some of the staff when I was lying in the ward forgot to bring me ice, water, but that's the way it is, I understand that they have a high workload and can't keep everything in their heads, so in the end they brought it a little later ) This is a trifle and the only small minus, I would not take it into account compared to the way they ran over me.

About Bookimed service

I accidentally found an advert on the internet and decided to just ask about rhinoplasty)))) In the end I had it done 😄 Although I didn't really plan to decide so quickly. The manager did his best, well done ))

I would definitely recommend this hospital and all the staff, I could not recommend them highly enough

The great experiance started from pick up from airport with private comfortable taxi to hotel, and the next day the taxi to hospital. The hospital was first class, clean to such a high standard with exceptional treatment and care, from everyone looking after us we could not fault it in anyway. The surgeon, anathesist, nurses and the interpretor, were all amazing, all looked after me so well and discussed everything that was going to happen and carried out several tests, l felt very comfortable in their hands and their hospital, my private room was amazing. My husband stayed in the hospital the whole time with me, where they catered for his needs, sleeping the night and supplying his food and drinks, making us both feel very comfortable. I would definately recommend this hospital and all the staff, l could not reccomend them highly enough. I will if l need more treatment, definately go back there. Finished with private taxi to airport, at no extra cost. Thank you all.

From start to finish l was made to feel very calm and relaxed and at ease all who looked after me were so kind and caring.

There was nothing that l didn't like. It was all amazing.
