Hi Carmen
I cant really offer first hand experience yet as my first appointment with a clinic in Barcelona is next month. Some of us ladies going to Spain have been posting on the ladies in waiting thread - I dont know if you have seen this. Basically I chose the Institute Marques as no waiting list (I could have seen them immediately but we could not fit it in until the 27 september), 70% success rate for ivf egg donation, good chance of frosties, ease of getting to barcelona, and very helpful when I e-mail - its the most expensive though compared with the IVI clinics.
Just wanted to say hi anyway and good luck.
Mandy
