Honestly, I'm in awe from this experience
The hospital was fantastic, room was private, with all required amenities, cafe - lovely, everything was beautiful and clean. Staff were just so accommodating, my Doctor was knowledgeable, explained the procedure in detail. Honestly, I'm in awe from this experience. And even though I was coming in with a slight fear and a tiny panic attack, there was really no need to worry, everything is on a highest level! Thanks to all!
Translators were top notch! Everything was amazing, I can't select just one thing.
Had issue with payment, it kept getting rejected and due to this I wasn't admitted right away. But once payment went through, all services followed smoothly.

But I really liked the Bukimed service - they helped, supported, organised everything in the best possible way
There are certain issues with the hospital, in particular, the staff who are in no hurry and we had to spend the whole day in the hospital instead of a few hours - we waited, waited, and waited again..... But I really liked the Bukimed service - they helped, supported, organised everything in the best possible way. Thank you.
Overall, the hospital is good
Perhaps it's due to a different mentality, but we didn't really like waiting endlessly - no procedure or appointment started on time, no one is in a hurry and no one appreciates other people's time.

I got more than value for my money
Memorial is more than a hospital. It is home from home. Very hospitable and caring staff who show a lot of empathy. My one night stay in the hospital was a delightful experience, kind and available staff, every neat and hygienic room. The doctors are on top of their job. I was taken through a lecture in nuclear physics 101, broken in simple language. The lecturer helped allayed my initial fears about the treatment. The treatment was speedy and the results came so quickly. The doctor was by my bedside to explain the next steps. The translator was fantastic. The transportation service was superb, always on time. I got more than value for my money. I will strongly recommend Memorial Sisli Hospital for any person seeking Lu-177 therapy
The ever presence of the medical support to attend to me in deep into the night.
May be the food could be improved in terms of quality served
