My stay in this apartment was one of the best. Room is very spacious and private, well furnished, like a suite in a hotel: there are TV, fridge, air conditioner, sofa (and there is welcome set on the table: bottle of drinking water, a plate of fresh fruits and cup of candies). There is a balcony in the room, air circulates very well if you keep windows slight open. There is a big bathroom, almost only for you, as the family lives in the other part of apartment (two apartment made one). Everywhere is clean with fresh odours, makes you extend your stay if possible. The apartment is in 2nd floor, but in Istanbul it is used to call this as the 1st floor. There are convenient stores, pharmacy, several cafes outside: fast food or traditional, not expensive, price starts from 40 TL (=$2.5). It takes 25-30 minutes by walking to reach seashore, 10 minutes to metro station.
And about family:
The Alp's family is one of the best family in the world: very friendly, welcoming and helpful. You feel you are with your friends. They treat guests with coffee and tea, offer dinners. Always smiling and never disturbs.
One will love the stay definitely.
