We go to ISCARE in Prague and they do a great job. Very good at explaining what happens when and making you feel comfortable with procedures. We have multiple fertility issues (PCOS, immune/clotting, motility, morphology, etc), so it took a while to find the right medication combination for me to be able to keep a pregnancy, but they finally got my combo of medications, steroids, and injections right! I really like that they do PICSI, vidoe monitoring, and immune treatments. Not a lot of clinics have all of those things. Their prices are very reasonable, their international patient coordinators are lovely (we have Zuzana as ours and she's great), and Dr Hulvert, the lead RE at the clinic, is the nicest doctor I have ever met in my entire life. They even let me bring in my own acupuncturist on transfer day and set me up with a private room to do pre- and post-transfer treatments!
If you need any advice on where to stay or places to visit while you're in CZ, feel free to message me anytime! If you want an acupuncturist recommendation for the area, I can give you that as well. Good luck!
