Our driver, Michael, was wonderful with a warm and helpful personality, but he didn't have much informaiton about the two sites we visited...by the way, we only found out a few days before that the Butterfly Valley was closed, so we chose to visit the 7 Springs instead. 7 Springs and, of course, Lindos are worth visiting, but it would have been better to have some information about both places from a guide. Greece can provide such exceptional guides, certified by the government, that is always a shame not to have one.
