We were staying in the apartment for one week. Shortly, the flat was great!
What was really brilliant is the view from 29th floor and how quickly Ilhan answered our questions. I don't know when Ilhan sleeps, but whenever I wrote him he always answered immediately and was ready to help :)
For example, there was no blanket sheet in the room because of the summer but we could not sleep without blanket. So we wrote Ilhan at midnight and got the blanket sheet.
The description says that the bed is more comfortable for single travellers. We were here as a couple and had no problem with a size of bed.
In general, the apartment is modern, stylish and cosy.
We found all necessary domestic staffs from dishwashing liquid to tee.
The apartment is a good start point for discovering the Asian part of Istanbul. If we have opportunity to visit Istanbul again, we will glad to stay in Ilhan's apartment. The only thing that I would take in the future is a sleeping mask. On the windows there are roller shades, but we like to sleep till noon and it is very sunny in the room at the morning.
