As a digital nomad, and not just a traveler, I have different expectations from the places I stay at. Gizem's place met all my expectations. It has everything I needed for a long stay. I love cooking and I really appreciated that the kitchen is well-equipped with a variety of pans and pots. The apartment is not cluttered and has enough space for storage. Though it's a garden apartment, it's pretty safe, with iron bars on all windows, so you don't need to worry about your stuff.
It's also very quiet and offered me the peace I need for my job. The internet is very good and fast in the living room.
The area is an authentic Turkish neighborhood. All necessary stores are just a minute away.
Bagdad Caddesi, the most central avenue is 10 minutes by foot. Bear in mind that the way back is not flat but thankfully not very steep when going uphill.
There is a bus running from Bagdad Caddesi to Kadıköy, but don't rely on that because it runs every 40 minutes. Go for a taxi van, "dolmuş" as it is called. You can find one in a matter of seconds and it's as cheap as the bus. Other than this, you can go a bit further down and catch the Marmaray train, which is very fast and gets you to the European side as well.
On the whole, if you wish the real thing, a comfy place and a long stay, Gizem's place is highly recommended.
