Renting this house in Istanbul is truly the best choice we made during the holiday, we were three and we had a great time from every point of view.
The location is great it's in the center of everything you might do on a city tour.
The apartment is spacious, bright and warm. You can look out the main door on a small terrace and see the Galata tower or from the other windows the skyline of the mosques on the other side of the Bosphorus.
Inside there is everything needed for 4 people from bathroom products or to organize a quick lunch.
Afik and Fazir are available for any eventuality and nice.
I would certainly recommend it to anyone who wants to spend a holiday in Istanbul, but I myself will take it again on a future holiday.
