My time in Iceland would have been so much less enjoyable if I hadn't booked Sam's coffee tour. He's an excellent guide - funny, generous, intelligent, and an unapologetic history nerd who knows a huge amount about Iceland's culture, society and history. The coffee was fantastic, of course - we drank lattes, espressos and filter coffees until we were shaking with caffeine. But the tour was just the start, and this is why Sam is such a credit to Vayable. I drank beer, ate food, bathed in thermal pools, explored art galleries and toured southern Iceland with Sam, his girlfriend, or people I met through them. Great guy, great tour.
