Engin's place was clean, comfortable, spacious and convenient. Engin was very helpful and communicated clearly. One aspect that was a bit surprising is that only the living room had AC, but the reality is that for my September visit the nights were cold enough that we did not need it in the bedrooms. All rooms had fans. Internet was quick and reliable. Location is very close to Taksim square but does require a steep uphill walk. I'd definitely consider staying with Engin at my next stay in Istanbul.
