We spent 4 days and 5 nights in Farouq's apartment, and it was really great! There were 5 of us: it was a family trip, but with special occasion – it was my sister birthday trip. So it was obligatorily for everything to be the best! And it was with Farouq's help! We had all we need in apartment + transfer from/to airport (even at 4 am). Farouq gave as a lot of advices about Istanbul: where to eat to be like a local, where to go for great views, where to have a really tasty breakfast (and believe me, it was cool), where to buy fresh and not-poluted fish, where are the best biosphere tours and etc. So, thank you, Farouq, we had unforgettable trip! Hope to come back someday!
P.S. If you want to stay close to all tourist place – Fatih district is all you need. This apartment is in few minutes walking to Blue Mosque and Hagia-Sofia. There are few stores near this apartment and some breakfast places. We cooked in apartment – there is everything for cooking. Street is quiet, but sometimes you can hear praying songs from Mosques.
