I stayed for one month. Katherine, her roomie, and the most beautiful kitten were all very friendly, polite, respectful and super super nice. The apartment is big, has high ceilings and it is located in a residential area. Great for working, wifi runs smoothly, and very peaceful, it is 2 blocks from a main avenue with plenty of bus stops, and coffee shops (there is even an Starbucks a 5 min walk away) and local restaurants. I don't cook but the kitchen is big, spacious, kept very clean. You can arrive to Kadikoy's center in 15 min by taxi or bus (there is a bus stop one block away). The room was big, there was plenty of light, and it has a little closed balcony with a lovely view. My favourite part was that my room felt very private as it is not even on the same floor than the other 2 rooms of the house. I recommend this place for a relaxing stay in Kadikoy. Bonus: The host is an artist so her paintings are all over her place.
