Let me start by saying how wonderful our guide, Mike was. Such a sweet man. Knowledgable, funny, and kind! At the start of the tour, he asked if anyone had any time constraints he should know about. We so appreciated this, as we had a reservation for tea that may have posed a conflict without Mike's help. He originally said he would try to take a more convenient approach into town so that he could drop us closer to our restaurant, but about half-way into the tour he told us that he would be dropping us off at the door of our destination! You really can't ask for better service than that - five stars go to Mike. The tour itself was also lovely. We enjoyed the drive to Malahide Castle, as well as the tour. The town of Howth was really nothing to write home about thus the four star rating instead of five, but I was glad to have gotten a glimpse of a seal.
