The reception is open 24h, the arrival was perfect, when we checked the apartment I didn't appreciate the floor and they proposed to me another one more interesting on my point of view of course I paid an extra but not too much for me, the apartment was clean the bed comfortable, the kitchen is fully furnished you need just to buy soap for the washing machine, I had one room and living room to receive people (it's not free you need to inform the responsible if they want to stay night). The bathroom is clean too.
I stayed 1 week, and they came to clean it one time it was enough for me!
To finish the price was nice compared to hotels around Istiklal place!

I recommend Güner's place.
