We had an amazing stay in Istanbul thanks to Ferhan and his hospitality! He was always eager to help and responded quickly to our queries. The place is clean, well equipped, and is ideally located in Kadikoy - walking distance to all the nice places, but still in a quiet street so you can get a good sleep.
Kadikoy is definitely one of the best places to stay in Istanbul. It is safe, has many places for a night out and you avoid the tourist traps of the European side.
Definitely recommended!
