The Short Answer
For most first-time visitors the best option is a guided tour covering Hagia Sophia, the Blue Mosque and the Basilica Cistern together, since the three sit within a 10-minute walk of each other in Sultanahmet and a guide explains what you're actually looking at — Hagia Sophia alone has been a church, a mosque, a museum and a mosque again across 1,500 years, which is easy to miss without context. Six real options are below, one for each priority — every one is a live listing you can message about before you pay: WhatsApp +91 84495 38716 or email, and a person answers.
