Susana was a great tour guide. She showed us the older areas-communities of Porto with curious information and lots of historical facts. She made it very entertaining and even though it was raining during the tour, she made the best of it and worth our every minute!
Had booked a tour for Monday several weeks in advance. The guru cancelled the tour the night before. The guru scheduled us for a tour the next day ( Tuesday) without our consent. The guru wanted us to cancel the new tour. - we declined. If the guru would have contacted us with advanced notification (more than 18 hours), this would not have been a problem. Instead, the cancellation created a problem with our day schedule and impacted our visit to Sintra. Perhaps the guru can improve communications with customers in the future.
