That's really good that he spent time with you and made sure you were ready.
My water baptism was in a swimming pool in Kona Hawaii where I was at the time doing a Discipleship Training School (DTS) through YWAM.
It was one of the best days of my life. I absolutely LOVE water baptisms. (when it's the real deal, of course) There's something about it that is indescribable.... pure joy, and it's hard to put into words but it's an amazing understanding that everything is brand new. That's why I love seeing water baptisms, because I know what a special day it is for that person, and I'm excited for them.
