Erol was very responsive and kind. I booked the room a free hours before switching and he replied immediately. The room is in the very centre of the city. 3 minutes from Taksim square and 10 steps from istiklal. It is very close to everything at any time of the day or night but because of that it is a bit noisy... Especially on Saturday we could hear the music from the clubs around till the morning. The other days was much much better. Overall a very good stay! Thank you Erol
