I spent two weeks at Murat’s apartment while in Istanbul visiting family. The apartment is centrally located in the middle of lively Galata. It is well equipped with everything that you will need for your stay and I felt comfortable there.
Public transport- tram, train, and ferry were all within a five minute walk which was very helpful. The apartment is within walking distance of shopping in Taksim, and the old city across the bridge.
There is a fantastic coffee shop ‘Java Coffee’ across the road, they will make you a flat white which will put hairs on your chest!
I would recommend Murat’s apartment.
