A fantastic stay; I can not recommend this apartment enough.
Central location: 5mins walk to Istiklal St (shopping, restaurants and bars galore), 5mins walk to public transport links (bus, metro) and a very short journey to all you want to see in Istanbul, 10mins walk to Taksim Square (where we got the airport bus). Despite being in the centre, it was extremely quiet!
The apartment is newly renovated with everything you could need, including wifi, a small kitchenette and great bathroom. It was the perfect size for two singles- Dilek arranged two double beds ahead of time, so we essentially had two private double rooms once the lounge was converted. If you struggle with stairs, be aware that the apartment in on the second floor and the stairs are quite steep.
All communication with Dilek was prompt, efficient and very helpful. She met us for check in and was available via WhatsApp for our whole stay. As guests were checking in the next day, check out was not midnight as stated on Airbnb for cleaning reasons. However, we were able to keep the keys and leave our luggage as needed!
Thank you again, Dilek!
