First: A big compliment to the host and his team.
Any questions or problems were handled very quickly and competently. Very friendly.
On the first day there was small problem with the heating, but this was fixed on the same day and then worked all the time.
The apartment is nicely furnished. There are a lot of closets. The living room is very cozy and large. There are candles, but unfortunately no lighter. That would be practical if you are a non-smoker yourself. We had 2x short power outage and candlelight would have been nice. :)
The apartment has the advantage that the windows of the bedrooms are not to the street side. This is very good in noisy Istanbul.
Unfortunately, you have no control over the neighbors. There are on directly in the apartment next door Arab neighbors who talk very loudly.
In the bathroom you sometimes smell cigarette smoke from the ventilation shaft.
Overall, the accommodation was good and we definitely give a recommendation for the host.
