We are so happy with the tile!! Josh & Cesar have done an excellent job of laying it and placing the varying colors in an attractive layout. And thank YOU for hand picking the tile for us. You chose a great assortment and there is enough of the brown, warmer tones I was hoping for.
It has been a pleasure dealing with you and your company. Josh is a real artisan and professional.
