We stayed for 9 nights at Haluk's. There were 8 of us, although the house was small for 8 people. It is written that the house is for 6 people.
Haluk was very helpful about the house, around the house and shops. He explained everything completely about the rooms and stuffs at check-in. He was available to answer and solve the problems in the house. We had problem with the shower, and tomorrow he sent a technician.
The duplex house was on the third floor near to Istiklal and Taksim Square (15-20 minutes). The bus station was a minute away from the house.
About the inside of house, upstairs was a bit warm, in August, because there wasn't air conditioner in that room. But there was a nice balcony as shown in the pictures.
The only problem that we had, was about the little insects in the house. We informed Haluk about it. he asked to come for spraying, but since some of us were allergic to insecticides, we refused.
To sum up, it was really good for this price.
