We had a lovely stay at Fatih's flat. He is a superhost and goes beyond to help his guests. The flat we stayed was clean, airy, and spacious. There is a small kitchenette for tea and light breakfast.
Location is nice with walking distance from the main street of Istanbul (Istiklal). You have to walk for 2-3 min to the nearest bus stop where buses can take you to Taksim square, and also 10min walk to the metro stop Shishane.
A small supermarket next door to daily basis such as water and fruits.
We will definitely stay again next time we are in Istanbul.
