Engin place was great!, great bed, great kitchen, great bathroom, great view. Looking the sunset in the bedroom window was awesome and very relaxing. You need to climb some stairs, and there is a mosque nearby, so you can hear the praying, the windows are very good, though. The communication with Engin was through Whatsapp and it was very good, he even helped me to throw out the trash and the recycling stuff haha. The self checkin was pretty cool.
I would definitely recommend this place to anyone visiting Istanbul, and will stay again here if I come back. Thanks Engin, and good luck!
