Combo (Save 13%): Entry Tickets to Galata Tower with Optional Audio Guide + Skip-the-Line Tickets to Basilica Cistern

Both the Hagia Sophia and the sunken palace were beautiful! It is very worthwhile. And especially for the Hagia Sophia, it's worth buying tickets online in advance to avoid the queue at the ticket office. It's also worth it for the Basilica Cistern, as there are 2 different queues here and the one for the e-tickets was quicker in our case.

The architecture of the basilica cistern is amazingly beautiful, very well lit and with a well organized traffic. It has generously met my expectations. But the number of visitors per shift or hour should be reduced.

Tickets were easy to book, great instructions and saved a lot if time by not queuing. In terms of the sites they were really good to see and understand the history behind it. Great addition to our Istanbul trip.

Easy to book. Very clear instructions from the guide in Topkapi, which helps not to miss the Harem and the incredible collections. Jump the queue ticket saved us waiting hours to enter. The experience in Topkapi, Hagia Sophia and Balisica were totally different and absolutely awesome.

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.
