Nice place to stay. I recommend it.
Only 5 minutes to walk to İstiklal street.
Things to mention to make your stay more comfortable:
1) In the bathroom, the faucet and shower switch may be broken. For the shower, pull the metal part up.
2) I did not immediately find that the heating is turned on by the water heater. This is common for Turkey, but may be unusual for tourists.
3) Try speaking Turkish. Learn a few simple phrases. Merhaba, teşekkür ederim, rica ederim, güle güle. The locals will be very pleased.
4) Enjoy your time.
