We were staying for 28 days and would totally recommend it.
Nice apartment, in the very center, 5 min to main street and Taksim square.
All appliances you might need are present and perfectly functional, gas stove (not on clock or tanks, permanent!), dishwasher, washing machine etc.
Balcony with a city view was a nice addition.
Ali Kaan was very helpful and hospitable, helped us a lot during our stay!
