I booked Pelins appartment for my parents as they were visiting me here at Istanbul. Both of them were totally satisfied with how the description and pictures were fitting reality. The appartment is cozy, neat and well furnitured. Besides its great amentities like free tea and coffee, extra blankets, shower jelly etc., the appartment shines by its location. Located at Cihangir, the most vibrant, pleasant and enjoyable district for me at Istanbul, it is so close to Taksim (metro) and the historical peninsula. Everthing for a touristic trip at Istanbul is at hand!
My parents agreed that they would stay again at Pelins place when coming for a second time to Istanbul!
Oh and I want to add that Pelin and her partner are really welcoming and caring. My parents arrived quite late in the evening and late check-in was no problem at all. And it was offered to us that if we encounter any problem that we could reach out for them and ask for advice or help ;)
