The surgeon was excellent
What surprised me most about my basalioma treatment wasn't the procedure itself, but the detailed skin examination I received. The surgeon was excellent. He made sure all removal options were discussed clearly, which was reassuring since I already had my diagnosis before arriving. Right now, the treated area is healing very well. While the medical care was superb and the clinic facilities are great, the administrative staff seemed a bit disorganized, which was the only downside. Despite that, based on the surgeon’s work, it’s a place I would suggest to others.
My Bookimed coordinator was highly skilled, had the passion and patience for her work and that translated to the numerous array of options provided to me to choose from based on my budget during the entire process.She interacted with me 24/7 just for us to have solution within my schedule. All information (proforma, visa assistance, travel guidance and estimated personal expenses) for the entire treatment were on point and I encourage all manner of persons seeking medical treatment abroad to choose Bookimed as their medical tourism partner.
1. Interpreter only come when the patient calls for his services and that is only during the day. If the interpreter can also support beyond the interactions with the specialist. 2. Airport and Internal movement are left to the patient to handle which can sometimes be a major challenge for some category of patients and given the language barrier. 3. Hospital discharges are very strict even if you the patient feels he/she need additional day(s) to be fit for a return to the hotel to continue the recovery.

The doctor and all the staff have been very attentive and professional, which gives me confidence that I made the right choice of clinic and treatment process
My main concern before starting treatment was how my body would react to the drug. I’m undergoing a course of Keytruda immunotherapy for kidney cancer, receiving an infusion every three weeks. Yes, I have experienced some side effects. These are mainly digestive issues, and I feel a little more tired. Of course, I am still concerned that these might get worse over time. But I must say that the doctor and all the staff have been very attentive and professional, which gives me confidence that I made the right choice of clinic and treatment process.

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.
