Staying at Serdar's place made for a wonderful trip in Istanbul. Sasha the co-host was always on hand if I had any questions.
The apartment is clean, modern, spacious and has all the amenities you'd need. It's a short walk away from the Galata Tower and it was great that it was tucked away in a safe lane and so we didn't get much noise disturbance. There's lots of food places about also and we were close to two main tram stations if you like to travel via public transport.
Would recommend to anyone wanting to stay in a cool neighbourhood with easy distance to the Old City.
