I would highly recommend bookimed to anyone needing a complex medical procedure
Our son was recommended to undergo a complex surgical procedure, which was not only risky but also extremely complicated. I couldn't be more satisfied with bookimed. From start to finish their representative Olha was professional, responsive and genuinely invested in helping me find the best possible care.
Olha took the time to understand my medical needs and concerns and provide personalized recomendatios for hospitals and surgeons of different regions. The information they provided was thorough and accurate.
The entire process was smooth and stressfree. All travel matters and documents were swiftly provided for travel procedures.
i appreciate the extra effort to ensure I was comfortable every step of the way. They kept a check on my son even after the procedure regarding his well being.
I would highly recommend bookimed to anyone needing a complex medical procedure .They have fully earned my trust and i feel grateful for their support during my challenging time.
the representative's swift and prompt response

كل الشكر لكم
زرنا مستشفى ليف بإسطنبول بناءا على نصيحة منسقكم السيد عماد حسين و تعاملنا مع قسم الاورام هناك بمساعدة السيدة فراح
الحقيقة المستشفى كان في المستوى و التعامل مع المريض كان جيد جدا
وقعت مشكلة صغيرة بخصوص ثمن الاستشارة الذي وصل الى 700 اورو بسبب سوء تفاهم مع المترجم لكن تم حل المشكلة و الاكتفاء بثمن الاستشارة 90اورو
شكرا على تعاونكم
نعم كان فيه تعاون كبير جدا من طرف السيد عماد حسين حتى انه كان يراسلني للسؤال و للاطمئنان على صحة المريضة
انسان فعال في عمله عند وعوده في الاتصال بالمستشفيات و واضح في لغته و لطيف في تعاملاته
كل الشكر لكم
