5 /5 Rafa Islam Diba: I booked a city tour and a NASA tour with this tour service and I have to say it was amazing! Everything was very organised and done on time. First I went into the cafe and checked in, then they gave me wristbands. I waited around until it was time to board the double decker bus which took us around the city and our tour guide, I believe his name was Ben, he was absolutely amazing. He made nice jokes, told us about the monuments, history and so much more which was very insightful. He was also very cheerful. 10/10. After the bus ride was over we were dropped at the same spot and after a 5-10 mins break we boarded the next bus to NASA space centre. They dropped us off around at 12 and picked us up at 4.20. Everything was pretty good, the staff were really nice and helpful. Would definitely recommend their services. I would suggest booking tickets online because it is cheaper compared to in person or their official site.
