The doctor is very competent, trustworthy, attentive, positive and charismatic
My father, 76 years old, had a knee replacement - Dr Olcay Guller. The doctor is very competent, trustworthy, attentive, positive and charismatic. This is important because my father was very worried and doubtful, but after the first meeting with the doctor he was completely reassured. All pre-operative investigations were organised quickly. Preparation for the operation and the operation itself - everything went smoothly. The next morning my dad was already walking along the corridor with the help of crutches. Nurses and nurses are attentive and friendly, no remarks. Feeding was also excellent, even a lot. I was placed in a spacious ward with a large window and air conditioning. In the bathroom everything is adapted for immobile patients, spacious barrier-free shower. On the territory of the hotel there are a couple of cafes with a good menu, Starbucks. The internet in the hospital is quite good.
All in all it was a pleasant experience. Would recommend the hospital with a clear conscience if needed
About Bookimed service
I don't know how long I would have searched for a hospital myself if I hadn't written to Bukimed. There was hardly any free time for this, and there were many doubts about the choice. With Bukimed everything unfolded quickly and in a couple of weeks my father was already seen by a doctor.

I want to say a special thank you to Marina for her help in choosing a clinic and all the work she did
Spent a day in the clinic. In general, the impressions are positive. The chamber is great. The only thing, it seemed that the nurses did not drop in very often - to find out about the condition, to carry out procedures. In Germany, in this sense, everything was more clear and on schedule. On the other hand, perhaps this is due to the simplicity of the operation itself and my condition. I really liked that we were always accompanied in the clinic. I want to say a special thank you to Marina for her help in choosing a clinic and all the work she did. And also thanks to Gulzara for always helping in everything within the walls of the clinic!

They made a big issue about accepting GBP and didn’t let me leave the hospital until payment went through. Staff were rude and the translator Muhammed is ignoring my messages asking for a revised letter.
