This was a wonderful place to stay while we were in Istanbul! IIker is a truly amazing host and got back to us almost immediately!
We picked the location because we had a wedding on the Asia side so being close to the bridge was important. With traffic, it's about an hour away from Old Town. There was an extreme Uber/Taxi shortage while we were there which made it very hard to get to places but luckily for us, the apt is close to lots of things. You can walk further away from the water and you have access to restaurants, grocery, liquor stores, bus, and metro stations. If. you walk towards the water you have access to a lot of restaurants along the water, there is a walking path that you could walk basically all the way to the New District and Old Town (it would be like a 2-hour walk but it's nice to have a safe place to walk :)) It was nice to escape the craziness of touristy places like Old Town and come back to our quiet neighborhood.
The apt was very clean and comfortable. There were 7 of us and the 1 bathroom wasn't an issue. The beds were comfy and we were able to sit in the living/dining room area and all chat and hang out. We'd love to come back to this apartment for a future Istanbul trip.
