Should I book a hamam on my first day in Istanbul?
Choose a time after you can realistically reach your hotel and settle in. Leave a buffer for flight delays instead of booking immediately after landing.

How long should I allow for a hamam visit?
Add changing, check-in and rest time to the advertised treatment duration. A 60-minute treatment does not mean you will be out of the building in exactly one hour.
What should I confirm before booking a hamam?
Confirm the exact address, treatments, total price, duration, privacy arrangement and appointment time. Mention any access or attendant requirements before paying or travelling.
How can I combine Sultanahmet sightseeing with a hamam?
Group nearby sights and leave a separate appointment window. For Golden Royal, use the address on Peykhane Sokak rather than a generic “Sultanahmet hamam” map result.
