Erol & Emre are amazing hosts.
Check in was super simple.
They were helpful if we needed anything.
Apartment is very cozy, petty and clean, but best part about it is location.
You are located literally 2 mins from the main street. From their place you can walk to Taksim square in 20 mins or in the opposite direction to Aya Sofia, Grand Bazaar etc in 30-40 mins. This makes it an ideal location as you are in between all of the places that you most likely want to explore.
Very high recommendations! Hopefully we get to stay here next time we are in Istanbul. :)
