Aysu was my host, she provided all the important check-in info through text and it was easy to find without problems. The space was very small, so if you have many big luggages, it will be hard to walk around. Definitely more suitable for single or duo light traveler.
Bathroom is small, but toilet was clean. Kitchen weren't perfect but its nice to have stove to cook something when we wanted to. We stayed in 1st floor, it was super loud outside on weekends with people talking and hanging out bar, even after midnight. But weekdays were fine.
Location is great, we walked by foot to most attractions. It's approx 20-30 mins walking to the other side of bridge (old town) and 15-20 mins to the Istiklal Street Shopping area.
Over all, its great for its location and price. I would recommend!
