My wife and I had a private wine tour in the Douro valley with Tommy and he was fantastic. Not only does he know everything about the wineries, he knows where to go in town for a great meal at local places away from the tourists. It was a pleasure to spend the day with him and learn about the Douro valley history and wines. If you are looking at using them for a tour just do it, we have a great experience and will recommend them to all our friends from the States as they visit this region!
