Pelin's place is located in the heart of culture in Istanbul. Cihangir is a charming neighbourhood with its quaint alleys and art / design shops. The cafe and bar scene is good and the place is very centrally located to the Topane train station.
Of course its a one time painful experience to drag luggage upto the third floor, but once settled in the apartment, it's fine. The washing machine in the store room is handy, especially when one is travelling for longer duration.
The apartment is small, which is the case with any apartment in a prime location of a city. so expectations should be set accordingly. Pelin is warm and helpful. And answers all questions patiently.
