I've stayed at Hilton Heliopolis last weekend. I really enjoyed my stay. The hotel is 3 minutes from the airport and 30 minutes from the Pyramids and Sphinx (on a Saturday morning 9am). Arrived at the hotel 5am, and was told that as a Gold I can be checked in as early as 7am. Great! I was directed to the bar Fuze. Had early coffee and beer (I was coming from KSA). I was also invited for breakfast while I was waiting for my room (very nice gesture).
Didn't get upgraded to executive floor so didn't had the chance to see the lounge.
The hotel has 12 on site restaurants. Yes, 12. Whatever you think of, they might have it. I wanted to order kusheri, but I've been told that Egyptian Nights restaurant is closed for Ramadan. Bummer. Instead of kusheri I had stuffed pigeons. Apparently another Egyptian specialty. I actually enjoyed them after passing the thought of eating the pigeon

All the hotel staff members were really friendly and helpful.
Had one mishap. After finishing breakfast and heading back to my room, restaurant manager and waiter run after me. Did I forgot something? No. I was presented with the bill for 29000 pounds for breakfast. Roughly $17. They didn't have my name on the list as "free breakfast" person. I've told them that I am HH Gold and that was it. They've apologized and went back to the restaurant. They were always nice about it, not hard feelings

At the check out I've inquired about it and my bill didn't have any extra charges from the breakfast restaurant (I had 2 in room dining orders from previous nights).
The breakfast spread had decent options. I think everybody can find something nice to eat there.
I didn't go to any of the restaurants during the day as I've been Uber-ing from place to place, just to kiss the door knob.
I really wanted to visit Air Force Museum (15 minutes walking distance from the hotel) and October War Panorama museum. When I got off from Uber at AF museum I couldn't find anyone. I've poked my head to the only one open window and saw soldiers drinking tea. Museum? Go to the gate. I went to the gate and was surrounded by 10 military guys with machine guns. Only 2 spoke limited English. Museum is here? Closed. Come back June 15... Damn it! They were very friendly. They don't see many "falangs" in that area, so that's why all 10 on duty soldiers came to "speak" to me. I had to shake hand with all of them. That was probably highlight of their day

Then I went to museum October War. Same thing. Closed for renovations.
Anyway, the next day I had tour scheduled for the pyramids. My guide arrived around 8:30am, I was given a call on my room phone and met with him.
The ride from the hotel to the pyramids took 30 minutes. On the way back little longer, about 45 minutes.
Check out took little longer (scan this card, sing here, sign there). Why? I already gave you my CC when I've checked in. After 10 minutes I was directed to the free shuttle bus to the airport. I was the only passenger. The ride took about 15 minutes as we had to stop at the mandatory military check right in front of the airport.
Overall, good hotel. I would definitely stay there again. Oh, and even this hotel is so close to the airport, you don't see or hear the airplanes. This hotel is close to departing runway, and far away from two arriving runways.
The only sound that I've heard was military practice shooting. They have a range right in front of the hotel (across the street)
