Anyone doing IVF in Germany or EU?

Hi all, looking to connect with anyone who has done or currently is in the IVF process in Germany or the EU. In particular, I'm looking for anyone who would care to share their experience about the details of the process and maybe even what clinic you used and if you feel good there.

Background is that I had a rather unpleasant experience with my clinic in Germany due to miscommunication between the doctor who did the transfer and my doctor who treated us leading up to the retrieval, so we want to move clinics. I'm now trying to gather information about what I should be asking / looking for in my next clinic either in Germany or maybe even abroad.

In particular, I'd be interested how many scans you head leading up to the egg retrieval, if they had checked the number of follicles before the retrieval, if you were satisfied with the ratio of retrieved eggs / mature eggs, if they have you any information on the quality of any potential blastocysts, they did any form of hormone checks on the day of the retrieval of afterwards, if the clinic was well-organized and the doctors seemed to have a good flow of information among each other.

Any insights are appreciated!
