I enjoyed a lot staying at Aysun's place.
The neighborhood is absolutely awesome: there are a lot of amazing places within a 5 minutes walk if you want to dine out, have a drink, listen to a concert or if you're just looking for original gifts/souvenirs ideas!
The room itself is very comfortable, sunny and, most of all, extremely quiet, which I appreciated a lot after coming from a full day wandering in Istanbul.
Aysun and her friend are kind and helpful, it was a pleasure to meet them and I wish I could have had some more time to get to know them.
Highly recommended.
