Igor is a wonderful tour guide. He is not only knowledgeable but he also a sommelier. So if you are a foodie, a wine connoisseur or a history buff, Igor is the only choice. Wait, did i mention he also worked in the service industry for over 20 years. He treats guests like family and the tour company he works for is run by a Canadian so you can understand the friendliness and the willingness to go the extra mile. Igor is my go-to in Porto moving forward. Not one negative thing about this tour or this person. Count yourself very lucky if you get to book Igor.
