Tolga's apartment is perfect for exploring Istanbul. The inside of the apartment has been tastefully renovated and offers good level of comfort at a good price. The location near taksim square is particularly convenient. The Havaist buses from either airport stops just a short walk away. By using the Taksim square metro you can get to all the major tourist attractions easily.
Tolga was a very helpful host and respond quickly to all our questions. He also owns other apartments in the same building and a pub nearby on the very popular Istiklal Street.
