This apartment was brilliantly located in a lovely part of Istanbul near lots of nice cafes, restaurants and a short walk to Taksim Square and a short downhill walk to the tram and ferry services (uphill on the way home though but that's a warning for anyone in Istanbul - it's a hilly city).
The apartment has good facilities, as far as I used. I didn't use the kitchen as there were so many great places to eat nearby.
Pelin is super helpful and very quick to respond to any questions you may have. I would definitely recommend her and the apartment and would stay again.
