Serdar is a great host, and the apt. in Çihangir was perfect for our 3 week stay in Istanbul. It is spacious for 2, the layout is great, it is very close to restaurants and cafés, there are banks and grocery stores close by, and you can see the Bosphore in the distance from the corner of the street. :) We loved going to Mello for dinner, and buying meze at Katina Meze Evo on Lenger sk. It was a great place to come back to after a busy day taking in the sights. The 15 min walk up to Taksim station suited us better than the steep one down to Tophane station. 5 stars all around.
