I was very uncomfortable that I could.not open the tickets.from email ortho app. Luckily, someone responded to my email quickly when I told them I was at the venue and not allowed in. I would use again, but have the actual tickets emailed to me.

It was a beautiful place, but it was too crowded and the worst part was I had trouble accessing the ticket because I didn't realize I had two so I didn't have good WiFi for a while so we had to wait to enter while they fixed it

We enjoyed both the Skip-the-Line-Tickets and touring the ancient Basilica Cistern. Basillica Cistern is a must-visit place for anyone who visits Istanbul.

We made a combined booking with Fastlane. For Hagia Sophia and Cisterna Basilica, the tickets we sent were immediately our valid tickets. Worked perfectly. Both sights were very beautiful and interesting. At Hagia Sophia, as a non-Muslim you "only" get to the first level and can look down into the whole mosque. Also very impressive, but not really explained beforehand. At the Topkapi Palace there was only one reservation in the mailing, which is easy to overlook, and we only noticed in front of gate 2 (where you need real tickets). We then had to go back to an agency outside Gate 1 so that we could finally get in with a tour lady. It worked but with a certain loss of time. The palace itself was huge and very beautiful. Be sure to book a ticket with harem access (as we had), this part is the highlight of the palace. All in all, a great day with lots of wonderful impressions.

Great place to visit but would have been better if details of how to get the included-in-price audio guide had been given.
Skip the lines and explore the Basilica Cistern with expert-led tours or audio guides.
Getting started
Arrive 10 to 15 minutes before your scheduled time and keep your mobile ticket and a valid photo ID ready. A staff member will meet you at the entrance and help you check in. You’ll breeze past the ticket queue, but do note that all visitors must go through a security check.
Basilica Cistern
The Basilica Cistern is one of Istanbul’s most atmospheric spots—a vast, ancient underground reservoir built in the 6th century. It’s best known for its forest of marble columns, the serene reflections in the water, and, of course, the mysterious Medusa heads hidden at the far end.
Depending on the ticket you choose, an expert guide will accompany you through the cistern. You’ll get the backstory behind the Medusa heads, learn how this shadowy space once supplied water to emperors, and hear quirky details you’d probably miss on your own.
Prefer to explore at your own pace? You can use the included audio app, available in five languages, to guide you through the cistern. If you want to see more of Istanbul, upgrade your ticket to include a guided tour of Hagia Sophia, an architectural masterpiece known for its massive dome and golden mosaics.
