Me and my friend travelled to Egypt last week. We stayed in Hurghada and decided to make a trip to Cairo. We booked the day trip by plane for 170 euros/person. It was the perfect choice. For a reasonable price, we were offered irreproachable services.
First of all, the driver that picked us up from the resort arrived right on time. At the airport, we met the rest of the group (a total of 7 tourists, including us) and we received all the necessary information regarding the flight. The flight itself was very pleasant, Egyptair provides a high level of comfort during flights.
When we arrived in Cairo, we met our guide, Mamdouh, who is, by far, the best guide I've ever seen. He was visibly passionate about his work, possessed great organisational skills (he used time wisely, nothing was done in a rush), interested in meeting all our needs, he advised us what to do and what not to do in order to be safe during the trip. He is a polyglot and easily switched from one language to another. At the Pyramids, he showed us unique places, with breathtaking landscapes, hidden from most of the tourists, where we took amazing pictures.
The driver in Cairo deserves a prize, he did miracles in those traffic jams that the city is famous for.
The next day, we travelled to Luxor with a different agency and we compared their services to Egyptra's, concluding that we should have chosen the latter one.
All that being said, I definitely recommend Egyptra for this kind of trip.
