This tour took my reservation even as a solo traveller. The "Black Taxi" company canceled on me in the early morning of the day of my tour so I booked these guys the last minute and they came through for me-literally booked at 3am and the tour was at noon.
I loved that they offer pick up service, firstly. As well, the guide and driver, Barry, was very friendly and immensely knowledgeable (also has has real life encounters and experience with the history of violence in Belfast).
We drove through the city and saw various murals, the peace wall, and memorials. I went in knowing very little about Ireland's history and left feeling like a history major, with all the information Barry shared with me. I even got some tips on my upcoming tours, where to eat/drink, and movies to watch about Ireland.
Highly recommend them!
