You will find some people who had different experiences - I don't know anyone who has had a good experience with them in the past 2 years (some have fallen pregnant but still didn't enjoy their time there) and that's out of 6 couples (1 of those fell pregnant 1st go with the only embies they managed to get but they still didn't like their journey or treatment and the other eventually fell pregnant but after a hard road) so I'm not sure what that really says considering the other 4 couples moved on from them.
My recommendation would be to ask plenty of questions. Don't hold back... if you ask heaps now you will see what kind of answers you get and see if they are enough for you. We asked a few to begin with and the answers were wishy washy but it only went downhill from there. The further we went the more questions we had and the worse the answers became.
I hope you have a better experience but think carefully about what you want from your FS and see if she really ticks those boxes.
