Stunning apartment and well located however catastrophic experience.
1- There was construction going on in the apartment with drilling and hammering noises all day. I had told the host that I was coming to work and rest. My host informed me that the construction had just started and that he would not have been able to warn me (but when I arrived it was visible that the construction had started days ago). I sense a lack of honesty here.
2- Water cut (a day from 10 PM to 12 AM). My host informs me that there is nothing he can do. I had to look on the internet myself to find out when the water would return. I still feel a lack of transparency on the part of the host.
My general impression of the hosts is not positive. They seemed to me to think more about their benefits than the well being of their guests.
Final remark: I did not appreciate the (unsympathetic) temperament of the hosts when I made my remarks. When I called the host to discuss, he spent 5 minutes telling me that he was in a hurry and had to leave. And when I left and asked for help to take my suitcase down (because there was no elevator) they refused. I had to find myself a person in the street to help me.
By experience, I know that there are more friendly hosts in Istanbul, so go to them rather than here.
