We stayed in three different locations during our two-week holiday in Istanbul and three different flats, respectively. Emrecan's place in Kadıköy turned out to be the best to my personal and the rest of my family's liking. It is in close proximity to all the relevant places in Moda and Kadıköy in general, be it the sea promenade or the multiple watering holes with lots of young and beautiful people. The vibe in Kadıköy was so different from Sultanahmet where we had spent a few days before.
Emrecan's flat can comfortably take three people and I got to realise that the fact that the host lets his own abode is actually rather advantageous: you find all the little things that are normally missing from places that are let out full time, such as all manner of cutlery, crockery and what have you. This is also in the true original spirit of AirBnB, letting out your place when you do not use it yourself.
We enjoyed staying at Emrecan's very much.
