Hagia Sophia is much more impressive from the outside as the inside has lots of scaffolding for the restoration work which our guide said had been going on for 50 years!
The interior is impressive but rather dark and it's difficult to get it all in.
The views from the balconies are good and you also get some great views of the Blue Mosque.
The admission price is 40 TL each and the queues can be very long unless you get there at opening time
