Farouq's place was amazing for my family. It is clean and there are nice amenities. The location is great and Farouq is a great host. We recommend Farouq's place to other visitors.
Advice for future guests:
1- This area in Sultan Ahmed is a great place but it is best to travel without a car as finding a parking spot is difficult. However, if you want to visit historic places you within walking distance so there is no need to have a car anyhow.
2- Apparently in Istanbul home numbers frequently get messed up and google may show the wrong location. You can enter the following coordinates in google maps, yandex or whatever to get the correct location:
41.003927, 28.970954
3- There are plenty of very good and traditional restaurants that are not listed in fancy websites (like google maps and foursquare). Just ask Farouq
