I couldn't have chosen a better place to stay in Istanbul! First of all, Zu is super nice. She let me check in earlier and her instructions were very easy to follow. She was busy at work, but we still had time to enjoy a chat in the evenings.
The house was very comfortable and clean, and most importantly, quiet! It was incredible to enjoy all that peace after a day spent in busy Fatih. The room has a view on the balcony/garden. It doesn't even feel like being in a city. At the same time, the Marmaray station is a 3-minute walk away and in 2 stops you're in the heart of old Istanbul! So you have the best of both worlds.
Her place can also be reached on foot (or 1 Marmaray stop) from Söğütlüçeşme station (last stop of the fast train from Ankara). It's also a good base to explore Kadıköy on foot.
There is a very nice greengrocer's just next door and some minimarts a few metres away.
Hot shower, WiFi and everything else was perfect.
I would definitely stay there again!
