Great apartment: it's 2+1 with spacious bedroom, dinner room and small room with additional bed (we didn't use it). Location is not superb, it's pretty far from the center but it's only 1 busstop away from the subway line. We spent pretty much all the time working so location wasn't a problem. Ayhan was really friendly, he met us the 1st day and was very helpful during our stay.
P.S.: don't go to the nearest forest, it's a military zone even though google maps says otherwise. On the bright side, Turkish police is very friendly :)
