Tarkan and Julia's apartment is wonderful. I went with a group of four friends for a long weekend in Istanbul. The location is perfect - you can walk to SultanAhmet for the main tourist sites but are already in the Karakoy and Beyoglu neighbourhoods in the evening, which is full of nice cafes, bars and restaurants. The apartment is beautiful and looks exactly like the photos - except the roof top which is even better in real life! Tarkan and Julia were also wonderful hosts, down to small touches like sharing a list of recommended restaurants and providing travel cards for local transport - to a very welcoming check in and help with airport transfers. Hugely recommend this apartment for anyone visiting Istanbul.
