We stayed two nights at Dominic and Marianne's place, to explore Santiago. Dominic has been a great host; picked us up from the airport and brought us back again, showed us how to best spend our little time in Santiago, had great suggestions for bars and restaurants. Without him we would definitely had a lesser experience in the city.
While talking we found out Dominic and his wife ran a restaurant and now organizes wine tours. Since he is a genuine nice guy, knows what he's talking about when it comes to wine and seems to know the region of Santiago as the back of his hand, I would definitely recommend him as your wine tour guide.
