The stay at Ahmet’s place was a good one, i recommend the place but keep a few things in mind first. The location is really good (few min away from istiklal, and about 5 min away from galata tower), it’s a calm area that is very close to a metro station; however, the area has many hills so probably it’s not the best place for those who have knee problems or for elders.
Ahmet the host responded fast when we texted him and he was very helpful when we had some issues.
The apartment itself was organized, with good internet access but it isn’t really sound proof as it’s an old building so be prepared to hear the 2nd floor neighbors’ steps. Also, the bathroom’s door is inside the bedroom so it might be a problem if there are more than 2 guests.
