The appartment is amazing,very clean,cozy,in a calm street close to taksim square.
Rose&Mustafa were available 24/24 for any question and they helped us immediately(example how to increase or decrease the central heater temperature or how to use the washing machine,easy check in and check out process...
I recommend to book this appartment for short or long stay in istanbul.
You don't need to bring anything with you!Everything will be ready there.
