the full experience was so very nice to navigate
Considering that we were traveling into Istanbul late on Saturday night, my support member was still texting with me and the doctor on a Sunday so that I was able to see the doctor Monday morning and then booked into surgery the following day. That would not happen other places, and the full experience was so very nice to navigate!!
With the help of Bookimed getting me in touch with the best doctor for my needs, I cannot be happier with the result of my surgery. The whole process was so easy and everyone involved was so very kind and helpful.
Only that I needed the procedure in the 1st place.
