They have the perfect place and spot in Istanbul, quickest responses I have ever seen, house is in a high-rise and, very safe with a hotel at the bottom on the resident, which you can use their restaurant or café, one of the best views in town, has everything you need in the house, the closest place to eat which they suggested is called Fiskane ( fish-khane) has plenty of restaurants to choose from and even a grocery store to shop, Aksaray and Istiklal RD, is with in 30 minutes driving, we rented a car and were allowed to park on premises.
We would highly recommend staying there and we would stay there again.
Thanks
