Great stay in Fatih!
The host, Güngör, is simply wonderful!
We had a delay (4h border crossing) and Güngör was so understanding and helpful.
The place is exactly what you expect from the description and photos: simply, clean and inviting.
The location is great: close enough to the main attractions in Fatih (short walk) and far enough from the main crowded streets so you can rest comfortably.
You also have public transportation options quite near.
It has 3 bedrooms:
1 room - 1 double bed
2 room - 1 double bed (smaller)
3 room - 1 single bed
1 living room (2 sofas, a lunch table)
It's not really clear from the photos but the apartment has a balcony (big enough) which we really liked (especially for the morning coffee).
All in all it's a great stay for 4 - 5 pers.
