British journalist living in Zurich
Jo and his group were a very serious group of travelers. All they needed was the direction of the metro station and it was like "ready set, go," They were gone every day and every night till very late hours. They were always polite whenever we ran into them but they had an agenda and they were busy. They were what i would call wonderfully serious travelers. They followed all rules for sure and left the place impeccably clean. Great group!
