We enjoyed our stay at Mustafa's place. Mustafa was a really helpful host. He told us the local places for shopping and eating. He offered us the last night at a very special rate. He also helped us keep our luggage at his place for few days while we went to Antalya. The place is super close (100-150m) to Taksim Meydani. You can get a metro to all the touristic spots. The staff was very helpful. The room was very spacious, and super clean. Our room was on third floor but the staff helped us take our luggage up and down. The building is on a very safe area. I will stay at Mustafa's place every time I visit Istanbul. I highly recommend Mustafa's place to anyone who wants to have a great time in Istanbul.
